biologists analyze a population of wild geese and determine that this particular population has a high level of genetic diversity. wild geese reproduce sexually. which of the following features of meiosis is most responsible for the genetic diversity in the wild geese?

Answers

Answer 1

The homologous double-chromatid chromosome pairs cross across and frequently swap chromosomal segments during prophase of meiosis I. In order to produce chromosomes with a diverse genetic makeup, this recombination allows genes from each parent to mix, resulting in genetic diversity.

What is meiosis I?The process by which most eukaryotic organisms—those whose cells have an ordered nucleus—produce sex cells, or the male and female gametes—is called meiosis. Two copies of each chromosome, one from each parent, are typically present in cells. The paired chromosomes are known as homologous, and this chromosome condition is diploid. One copy of each chromosome is found in each of the four haploid granddaughter cells that meiosis creates from a diploid cell. A species' genetic diversity is boosted through the procedure.Two cell generations go through meiosis at once. Each chromosome undergoes a normal cell division process called mitosis during which it is duplicated, resulting in twin sister chromatids on each chromosome. To create the following generation of identical chromosomes, these linked chromatids later split during mitosis. Each daughter cell only obtains one copy of each chromosome, or the haploid number, and each copy contains two chromatids during meiosis I since the chromatids do not separate during this process. The chromatids split apart and are dispersed to each gamete that is produced during meiosis II.

According to a 2013 study by the Center for Biological Diversity, almost 10% of the ESA-protected species are recovering at the rate projected in their recovery plans.

Every living thing, from people to organisms we know little about like bacteria, fungi, and invertebrates, is included in biodiversity. This includes not only the species we deem uncommon, imperilled, or endangered but also every other type of living thing.

We consider people and the diversity of human cultures to be an aspect of biodiversity at the Center for Biological Diversity and Conservation. The concept that the social and biological facets of life are intertwined and that people and places are dynamic, always changing, and interconnected is what we refer to as being "biocultural." According to this idea, human behaviour, knowledge, and beliefs have an impact on natural systems, of which human societies are a part, and are also affected by them. All biodiversity, including species, landscapes (land and sea), and cultural ties to our homes, are made to be true by this relationship.

apes what is the likely response of the island vegetaion after the elimation of the invasive european rabbits

Answers

Wild rabbits harm vegetation, compete with local species, and ruin the environment. By devouring seeds and seedlings, they ringbark shrubs and trees and stop regeneration.

Rabbits frequently have a greater influence during times of drought and right after a fire, while food is scarce and they have to consume whatever they can.Additionally, phosphine and carbon monoxide are employed to fumigate burrows & kill any rabbits that may be present. It appears that spreading viruses into the wild is the best and most economical strategy to reduce the population of European rabbits. Native fauna and flora are directly harmed by rabbit damage and competition for food and shelter. They destroy vegetation through their burrowing and browsing, which can cause soil erosion and slope instability. Additionally, because of their excessive grazing habits, which frequently cause soil erosion and decreased water quality, rabbits compete with native species for food and habitat. The first step in managing an invasive species is recognising rabbit activities on your property.

Answers

Warm water runoff that reaches lakes and ponds slows down the metabolic rate of aquatic animals, which decreases primary productivity best describes how thermal power plants can affect aquatic ecosystem.

Thermal pollution refers to any change in a habitat's natural temperature, and it can take many different forms, from the discharge of cold water into nearby streams to the increased temperatures associated with industrial cooling activities disturbing the aquatic ecosystem. Thermal or nuclear power stations, industrial effluents from steel mills, pulp and paper mills, chemical plants, refineries, as well as sewage effluents, are the main sources of thermal heat pollution. The most important condition for aquatic species' survival is the water's ambient temperature. Because temperature increases limit enzyme activity, aquatic plants have a lower rate of photosynthesis. Thermal pollution causes water bodies to become warmer, which reduces the primary productivity and species diversity of aquatic plants. Fish and other species acclimated to a specific temperature range may therefore be killed by the sudden shift in water temperature when a power plant first starts up or shuts down for maintenance or other reasons.

Answers

Based on the number of MN blood group genotypes, they are not from the HW data, possibly due to the Wahlund effect of interbreeding with neighboring tribes (or maybe inbreeding)

In population genetics, the Wahlund effect is the buildup of heterozygosity (ie when an organism has two different alleles at a locus) in a population caused by the structure of subpopulations. That is, if two or more subpopulations are in Hardy-Weinberg equilibrium but have different allele frequencies, the overall heterozygosity is less than if the entire population is in equilibrium. The underlying cause of this population subdivision could be a bottleneck to the geographic flow of genes followed by genetic shifts within the subpopulation.

Genotype frequency:

MM (p2) = 400/2000 = 0.2

MN(2pq) = 1200/2000 = 0.6

NN (q2) = 400/2000 = 0.2

Allele frequency:    

Frequency M = p = p² + 1/2 (2pq) = 0.2 + 1/2 (0.6) = 0.2 + 0.3 = 0.5

Frequency N = q = 1-0.5 = 0.5.

Expected genotype frequencies (assuming Hardy-Weinberg):

MM (p²) = (0.5)² = 0.25

MN (2pq) = 2(0.5)(0.5) = 0.5

NN (q²) = (0.5)² = 0.25

Expected number of individuals from each genotype:

MM = 0.25 X 400 = 100

MN = 0.5 X 1200 = 600

NN = 0.25 X 400 = 100

CHI-SQUARE (X²):

X² = Σ(O-E)²/E

X² = (400-100)²/400 + (1200-600)²/1200 + (400-100)²/40

X² =225 + 180 + 200

X² =630

X² (Calculated) > X² (table), then reject the null hypothesis. Not on HWE.

Therefore, conclude there is a statistically significant difference between what was observed and what was expected under Hardy-Weinberg. That is, the null hypothesis is rejected and concludes that the population is not in HWE. They don't, possibly due to the Wahlund effect of interbreeding with neighboring tribes (or possibly inbreeding).

Answers

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell undergo increasing repression.

What do you mean by repression?

Repression is a psychological defense mechanism whereby a person unconsciously blocks unacceptable thoughts, feelings, and memories from their awareness. It can involve the denial or suppression of desires and impulses, or even the distortion or transformation of such desires into more acceptable forms. Repression is a defense mechanism that is used to keep potentially threatening or uncomfortable information out of conscious awareness.

Cellular differentiation is the process by which a single cell divides, resulting in two or more specialized cells that have different functions. As this process occurs, the cell's gene expression profile changes, with some genes becoming more active and others becoming increasingly repressed. This is done in order to ensure that the cell will be able to specialize in performing certain tasks and that it will not become confused and perform the wrong function. As the cell's gene expression profile changes, the number of genes that are expressed reduces, restricting the range of functions the cell can perform. This increasing repression of genes restricts the cell's fate and ensures it will specialize in performing a specific task.

What is herbivory ?The genetic underpinnings of trichome density induction have not been studied, but previous research on A. thaliana has demonstrated an increase in trichome density in response to leaf damage, suggesting a mechanism by which the cost associated with constitutively high trichome density might be mitigated.Here, we describe the mapping of quantitative trait loci (QTL) for constitutive and damage-induced trichome density in two new recombinant inbred line populations of Arabidopsis thaliana; mapping for constitutive and induced trichome density also allowed for the investigation of damage response (plasticity) QTL. The first QTL for induced trichome density and response, as well as novel and previously described QTL, are found. It is interesting to note that two of the four parental accessions and numerous RILs in each group showed decreased trichome density after leaf injury, a reaction not previously seen in A. thaliana. Intriguingly, a single QTL was identified for the response phenotype, and allelic variation at this locus seemed to control the response trajectory in RILs. The information demonstrates that trichome density's genetic architecture includes epistatic interactions as a significant element.

It enables the bacterium to create a latent and incredibly resilient cell to protect the cell's genetic material under extremely stressful conditions. Endospores are able to withstand environmental stresses that would typically kill the bacterium.

What species of bacteria make endospores?

Nevertheless, low G+C Gram-positive bacteria, such as those belonging to the genera Bacillus, Clostridium, Thermoactinomyces, Sporolactobacillus, as well as Sporosarcina, produce practically all of the endospores.

Which of the following events happens at the conclusion of meiosis I?
A) Four daughter cells are formed.
B) Homologous chromosomes of a pair are separated from each other.
C) The chromosome number per cell remains the same.
D) Sister chromatids are separated.

Answers

At the end of meiosis I, a pair's homologous chromosomes are split from one another.

What occurs once meiosis 1 is complete?

When each homologous pair of chromosomes reaches the opposite poles of the cell, meiosis I is complete. Each haploid set of chromosomes is encircled by a fresh nuclear membrane once the microtubules break down. When the chromosomes uncoil, new chromatin is formed, and cytokinesis takes place, two distinct daughter cells are created.

At the end of meiosis, which of the following occurs?

The two cells are then physically split apart by a process called cytokinesis. Four haploid daughter cells remain after meiosis, and these cells can differentiate into either sperm or egg cells.

Explain how genetics and environment influence the similarities and differences within twins

Answers

Answer:

Because identical twins share all of their genes, their measurements of IQ and sleep time will be more similar the bigger role genes play in it (i.e., differences between two identical twins must be caused by the environment because their genes are the same).
