Question

In single-gene traits, natural selection can lead to which of the following?

a. Allele frequency change
b. Directional selection
c. Disruptive selection
d. Founder effect

Answer 1

It causes the allele frequency to resemble that of a small number of individuals that became separated from the rest of the population.

Answer 2

Answer;

-Allele frequency change

In single-gene traits, natural selection can lead to allele frequency change.

Explanation;

-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.

-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.
