Scientists have discovered and analyzed a huge number of fossils that represent a wide variety of species. What type of evidence
Rainbow [258]

Answer:

The fossil record supports a "biological" type of evidence.

Explanation:

<u>Fossils-</u> this refers to the <em>remains of prehistoric organism.</em><em> </em>It provides a trace of a <em><u>once-living plant, animal or organism. </u></em>

When it comes to evolution, fossils provide a biological type of evidence. This means that,<u><em> it shows how organism have greatly changed from the past.</em></u> When you study fossil records, you can compare it with the animal, plant or human structure nowadays. You can compare them side-by-side. So, you'd get that idea on how prehistoric things lived in the past and how they evolved up to the present day or became extinct.

<em>Most of the fossils can be found on sedimentary rocks.</em> You can also tell their ages according to which layer they belong. It is said that older layers consist of older fossils and they appear at the bottom while younger layers consist of younger fossils and they appear on top.

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. What is the
Illusion [34]

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. The frequency of individuals that are heterozygous for this allele is 0.32.

<h3>Hardy Weinberg Equilibrium Principle </h3>
  • A stable, idealized population's constant frequency of alleles and genotypes is described by the Hardy-Weinberg equilibrium principle.
  • In a sizable population, random mating, or spontaneous mutations are necessary for Hardy-Weinberg equilibrium.

The Hardy-Weinberg equation dictates that the sum of the allele frequencies for each allele at the locus must equal 1, therefore p + q = 1. The Hardy-Weinberg equation is also written as p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is that of the "a" allele.

The homozygous genotype AA frequency is represented by p2, the homozygous genotype aa frequency by q2, and the heterozygous genotype aa frequency by 2pq in the equation.

Here, q = 0.2. Because of this, p = '1- q = 1 - 0.2 = 0.8.

The population of individuals who are heterozygous will now be 2pq, or 2 * 0.8 * 0.2 = 0.32.

Hence, This indicates that the population is heterozygous with a frequency of 0.32.
