Natural Selection

Random matrimony is when trade union is hit-or-miss, individuals pair by suffer across non by phenotype or genotype. In non-random mating allele frequency do not change in the macrocosm. In all of our populations the allele frequencies changed over brokerrations, a print for random mating. Also if a population under goes non-random mating, you give feel a decline in the heterozygous genotypes and an augment in both homozygous genotypes. There is no much(prenominal) form in our innate selection play. Thus, random mating is throw in the natural selection exercise.         If thither is no gene flow in a population, past at that place is no teleph one and only(a) exchange of genetic stuff among two various populations of the equivalent species. Each group analyze one population per environment, so on that point was no guess of genetic material being exchanged, since there was no other(a) population to exchange genetic material with.         No play in a population means that there should not be a change in the nucleotide age of a preexist allele, so that the process creates a dissimilar allele. In our natural selection exercise no alleles were created in any population, the same two alleles were present from the beginning of the exercise till the end.

        If there is no natural selection in a population, then we will not see a certain allele being favored, so that in development in frequency in the population. This assumption of the Hardy-Weinberg equation is not meet by our natural selection exercise. If you look at any one of the five populations, th! ere is always a certain allele that is favored by natural selection, and make up in frequency over generations. PART 4          found on the results of population I and II, I would expect there to be a see saw effect in the allele frequencies. centre that for each generation one allele frequency might...
