The mechanism to the following statements are:
a. The transfer of genes from one population to another is gene flow.
b. Drives the changes that occur in populations are due to natural selection.
c. A permanent change in the DNA sequence of a gene is mutation.
d. The random change in the frequency of an allele in a population is genetic drift.
What is the variation?
Variation is the difference in DNA between individuals or between populations.
Mutation and genetic recombination, natural selection, genetic drift are all the many origins of genetic diversity.
Thus, the correct mechanism is a. gene flow, b. natural selection, c. mutation, d. genetic drift.
