Which of the following is not a factor influencing the amount and kind of genetic variation present in a population?
a)Assortative mating.
b)Immigration.
c)Mutation.
d)Random genetic drift.
e)Selection.
Homework Answers
Ans: e) Selection- Selection usually promotes those individuals who are only best adapted to the environment living in a particular area to survive and reproduce its offspring. Genetic variation arises as a result of mutation, recombination, random mating and random fertilization. Assortative mating and immigration of genes has also been studied to result in an increase in additive genetic variance.

Natural selection can move a population beyond its initial range of variation because a. sudden increases in mutation rates are often induced by selection. b. under genetic drift there is less variation and under selection there is more. c. selection can expose hidden variation. d. selection usually increases the randomness of mating, thus increasing variation.

Which of the following statements about genetic drift as an evolutionary factor is true? a. It is more potent in a population with small numbers than in a population with large numbers. b. It is responsible for the selection of mutations. c. It is connected to the movements of alleles between populations of a single species. d.
