Question

What are the five assumptions that are made about a population that is in Hardy-Weinberg equilibrium? Detail how violations of each assumption can alter the frequency of genotypes in a population from HW expectations. A complete answer will indicate whether violating the assumption is likely to consistently increase the frequency of homozygous or heterozygous individuals and explain how this happens. (Note: You will be given one or two assumptions in the test but you must be prepared to answer for any of them.)

For this question, for each of the 5 assumptions, the increase or decrease of homozygous and heterozygous, it all depends on what genes are being introduced or deleted, so do we create a hypothetical situation for each of the assumptions. Natural selection for instance, homozygous can be selected or heterozygotes, and if homozygous is being selected, we don`t really know if it is homozygous recessive or dominant (if dominant then heterozygous will also be selected). Ill deifnitely give you a thumbs up if you give me a sample source population for each assumption and how homo and het will be affected...

Explanation / Answer

Assumption 1: No Genetic Drift

Sexual reproduction recombines genetic information in a random pattern. In a small population, it is possible that few individuals carry an allele and simple chance could make them more or less successful in passing on that allele. So there are 50% chance to the population for becoming homozygous or heterozygous.

Assumption 2: A Closed Population

Emigration and immigration that is, transfer of individuals into and out of a population can change the frequency of alleles. Emigrating individuals might take more of one allele out of a population, and immigrating individuals might come from a population with a different proportion of alleles. The gene flow of different individuals might affect the selection of the homozygous and heterozygous population.

Assumption 3: Mutations Don’t Happen

Mutations are errors that happen when DNA is being copied. Mutations can change the organism in a population to adapt, survive and reproduce. similarly, they can become harmful to the population causing survival instability. This should lead to affect the homozygous and heterozygous population.

Assumption 4: Random Mating Patterns

The Hardy-Weinberg principle assumes that every individual in a population has an equal chance of mating with every other individual, totally random mating. Random mating has the higher chance of affecting the selection of Homozygous and heterozygous.

Assumption 5: No Natural Selection
