Which of the following will change genotypic frequencies in a population without also changing allelic frequencies?

A. Assortative mating

B. Genetic drift

C. Migration

D. Natural Selection

E. All of the above change both allelic and genotypic frequencies

Expert Solution

Answer:

Correct Option is E: All of the above change both allelic and genotypic frequencies

Assortative mating is a type of non-random mating, where individuals having similar phenotypes mate with each other more frequently than would expected under a random mating pattern.
This evolutionary agent violates the Hardy-Weinnerg equilibrium and it can change both allel and genetic frequencies in a population.
According to the principle of Hardy-Weinnerg equilibrium Genetic drift,Migration and Natural Selection are all against the principle which causes both allel and genetic frequencies to chang in a population.
Hardy-Weinnerg equilibrium states that in a population the allelic frequency and the genotype frequency will remain constant from generation to generation if there is no mutation, no natural selection, no gene flow, large population size and random mating among the individuals in a population.

A small portion of a population migrates to an isolated island. Its genotypic frequencies are 0.8 AA, 0.1 Aa and 0.1 aa. These individuals start a new population on this island. What phenomenon is being described here? Calculate the allele frequencies for this new island population. Assume that this population is not undergoing evolution and undergoes random mating. What genotypic frequencies will you see in this population after one generation of random mating? What will the allele and genotype frequencies...

A population has the following genotypic distribution: 10AA 15Aa 25aa. Based on your calculated allele frequencies, how many individuals would you expect to be homozygous dominant (=AA) if the population is in H-W equilibrium? Based on your calculated allele frequencies, how many individuals would you expect to be heterozygous (=Aa) if the population is in H-W equilibrium? Based on your calculated allele frequencies, how many individuals would you expect to be homozygous recessive (=aa) if the population is in H-W...

Question 6: Calculate the genotypic frequencies that you would expect if the population is in Hardy-Weinberg equilibrium. (Remember, that we are preparing to use the Chi-square goodness-of-fit test to determine if this population is in fact in Hardy-Weinberg equilibrium). Round your answer to three decimal places and submit your answer in the correct format (e.g. 0.062). (a) The frequency of the SS genotype is: (b) The frequency of the Ss genotype is: (c) The frequency of the ss genotype is:...
