A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.

Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.

Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).

What are chromosomes? When do chromosomes form?
defon

Answer:

Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

Hope this helped! :)

All of the following are transmembrane pumps that facilitate active transport except?
BigorU [14]

Answer:

b) Channel pumps

Explanation:

The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.

For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.

The goal of the world resource simulation center is best described as _______. a. solving current problems regarding world resou
uysha [10]

The goal of the World Resources Simulation Center (WRSC) is best described as: C. determining how to manage global resources for all humanity.

<h3>What is the World Resources Simulation Center (WRSC)?</h3>

The World Resources Simulation Center (WRSC) can be defined as a non-profit visualization and simulation facility that is saddled with the responsibility of availing individuals an opportunity to view critical trends about global global resources.

This ultimately implies that, the goal of the World Resources Simulation Center (WRSC) is best described as determining how to manage global resources for all humanity.

A man and his wife both have normal color vision, however their daughter is positive for red-green color blindness. The man sues
mixas84 [53]

Answer:

Man's genotype: XᴮY

Woman's genotype: XᴮXᵇ

Daughter's genotype: XᵇXᵇ

The daughter is not the man's child.

Explanation:

Color blindness is a sex-linked trait caused by a recessive allele located in the X chromosome (Xᴮ=normal vision; Xᵇ-color blind).

Women have two X chromosomes, while men have an X and a Y chromosomes. For that reason, women need to have two recessive alleles to be color blind, while men only need one Xᵇ to be colorblind.

Since the man has normal color vision, his genotype would be XᴮY.

If the daughter is her father's, she would have inherited his dominant Xᴮ allele, so she would have normal vision. However, she is colorblind, so her genotype is XᵇXᵇ. She is not the man's daughter.

The mother also has normal color vision, but her daughter inherited a recessive allele from her, so her genotype is heterozygous XᴮXᵇ.
