0.36AA + 0.48Aa + 0.16 aa = 1
The ratio of genotypes in a three-allele system is determined using the Bernstein formula. r ² + q ² + g ² + 2rr + 2rr + 2qr = 1
where the amount of r-A gene; amount of q-V gene; amount of r-S gene;
as well as p + q + r = 1
For example, rA = 0.5; qV = 0.3; If rS = 0.2, then: AA = r ² = 0.5 ² = 0.25 VV = q ² = 0.3 ² = 0.09 SS = g ² = 0.2 ² = 0.04 AV = 2rq = 2 (0.5 * 0.3) = 0.30 AS = 2rg = 2 (0.5 * 0.2) = 0.20, VS = 2qr = 2 (0.3 * 0.2) = 0 , 12
The sum of the genotypes is as follows. 0.25 + 0.09 + 0.04 + 0.30 + 0.20 + 0.12 = 1
The similarity of the two populations is determined using the Mayal-Lindström formula: 
 
where x and u are the amounts of the same alleles in the populations being compared.
The degree of homozygosity of individual populations is found by applying the A. Neumann Sorenson formula.
Sa = | r ₁ ² + r ₂ ² + r ₃ ² + ... p _n ² * 100
where r ₁ r ₂ , p ₃ are the frequencies of the individual alleles. 
The evolutionary nature of genetic variation within populations
You have studied the combination of new genes that are present between generations in the sexual reproduction of a population above. Let’s look at genetic variation in population change. Darwin restored the population by developing a variant of differentiated reproductive success organs.
Ten of the best kits were planted in locally permitted soil (environment), thus tracking their gene. The results of natural selection were obtained from a set of genetically modified, suitable for the environment. If we change the good environment of the population, in each generation (generation), with the least amount of new condition, it will be effective.
The source of mutations of different alleles, which they mix and compete with during meiosis, becomes the population. New and different combinations of alleles can work better if preceded.
The ability to reproduce is based on genetic diversity and is one of the best that has been routinely analyzed for evolutionary rigidity in the process. In many other cases, asexual reproduction in a constant environment can grow in a favorable environment because successful combinations of alleles are kept constant.
Sexual reproduction is not expensive, their energy is reduced in value in the body from sexual reproduction, the answer to which is given in the following sections. Sexual reproduction in an unfavorable condition is almost unheard of among animals that we do not know, and the ability of some species to retain asexual reproduction of animals under excellent conditions has always been considered completely unique.
An example of this is a group of microscopic animals called bdelloid rotifes. They live at the bottom of lakes, ponds, near trees and many decay.
According to recent readings, the transition of these animals from sexual reproduction to asexual reproduction was a successful discovery in evolution. Biologists have found other mechanisms in the reproduction of genetic diversity in the body. For example, they lived in dry conditions for a long time, during which time the animals would go inside.
In this case, their cell membranes become a DNA organ and enter the green rotifiers. Based on this evidence, the rotifer genome was added to this DNA, leading to genetic diversity.
Using these, a useful convenient evolutionary, genetic variant was created. This species has developed bellou rotifers in the mechanisms of genetic change.
Mendel published a theory of Darwin's contemporaries inheriting genetic changes, but his discovery shocked many biologists. Mendel discovered the basis of management by selective inheritance of selection behavior.
