Analysis of Genotypic Distributions within Six Population Groups Using Assignment

Analysis of Genotypic Distributions within Six Population Groups Using Genepop Software - Assignment Example Which in essence, states that frequencies of alleles and genotypes remain constant in a population under ideal conditions. A balanced equilibrium should persist throughout the generations barring specific disruption. Disruptions in this equilibrium include non-random mating, selection, mutations, population-bottle-necks or other events that limit population size. The mating overlap between generations, meiotic drive, genetic drift or gene flow. As it is impossible to eliminate all of these conditions at some time from a population, Hardy-Weinberg equilibrium is impossible in nature. But this principle is a useful baseline against which to measure changes that do occur. Static frequencies of alleles throughout a population require a set of theoretical assumptions; deviations in which can give us information about which genes are changing in what way. These assumptions are : Violations of the Hardy–Weinberg assumptions trigger deviations from the expected status quo. The effect depends on which assumptions are broken. The character of these variations is thought to define the evolution of a species. When a population violates one of the assumptions listed below, the population may continue to exhibit Hardy–Weinberg proportions each generation, but the allele frequencies will be shaped by these deviations. Migration. The way in which two populations are genetically linked. Essentially, allele frequencies blend into homogeneity between the populations. Some models for migration must assume nonrandom mating. Without this randomness, the Hardy–Weinberg assumptions will not be valid. Random mating. The HWP states the population will exhibit a given genotypic frequency following a single generation of random mating within the population. When this assumption is broken, the population will not match Hardy–Weinberg proportions.
