If you are talking about bars with horizontal lines on either end, that is an error margin bar

A population of 200 mice contains 168 brown mice. brown is dominant to gray. how much of the population would be heterozygous?

Ainat [17]

84%

84% of the population of mice would be heterozygous.

<h3>What does heterozygous mean?</h3>

Heterozygous refers to the presence of two different allele types for the same gene. For a single gene, these alleles display two distinct character types. An illustration would be someone with an allele for both brown and black hair.

There are 200 mice in total, 168 of which are brown.

By the Hardy–Weinberg (HW) equilibrium

q² (bb) = (200 - 168) /200 = 32 / 200 = 0.16

q: √ 0.16 = 0.4

p = 1 - q = 1 - 0.4 = 0.6

p² (BB) = 0.6 x 0.6 = 0.36

Thus, 84% of the population of mice would be heterozygous.

<h3>What is meant by population heterozygosity?</h3>

Given that q2 is significantly smaller than 2pq when q is close to zero and p2 is significantly smaller than 2pq when p is close to zero, rare alleles are mostly found in heterozygotes.
This is known as population heterozygosity.

once genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the process

Yanka [14]

Once genetic genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the processes of genetic drift, mutation, and natural selection. The process which is more likely to be the slowest is mutation.

<h3>What is mutation ?</h3>

A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

<h3>What is genetic drift ?</h3>

Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.

<h3>What is natural selection ?</h3>

An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.

Thus from above conclusion we can say that once genetic genetic isolation separates two populations from each other, genetic divergence begins to happen as a result of the processes of genetic drift, mutation, and natural selection. The process which is more likely to be the slowest is mutation.

Air pollution is best defined as ________.

Tresset [83]

Answer;

A. gases or particles present in high enough concentrations in the atmosphere to harm humans, other organisms and structures.

Explanation;

Air pollution is a type of pollution that occurs when harmful or excessive substances such as particulates, gases and biological molecules are introduced into Earth's atmosphere.

The burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles is the major cause of air pollution.
