Following genetic drift,
a. genotype and allele frequencies would not change.
b. genotype and allele frequencies would change.
c. adaptation would occur.
d. the population would have more phenotypic variation but less genotypic variation.

Key Concepts

Genotype Frequencies

Genotype frequencies pertain to the distribution of genetic combinations (genotypes) in a population. Just like allele frequencies, they are subject to change through evolutionary processes such as genetic drift, which can randomly alter the genetic composition of a population over time.

Adaptation

Adaptation in evolutionary biology refers to the process by which a population becomes better suited to its environment through natural selection, where beneficial traits that enhance survival and reproduction become more common. It differs from genetic drift, which is a random process and does not necessarily lead to traits that improve fitness.

Genetic Drift

Genetic drift is a mechanism of evolution that involves random changes in the frequencies of alleles within a population. These changes occur by chance, especially in small populations, and can lead to the random fixation or loss of alleles regardless of their impact on survival or reproduction.

Allele Frequencies

Allele frequencies refer to the relative proportions of different forms of a particular gene within a population. Changes in allele frequencies are critical for understanding evolutionary processes, as they indicate how genetic traits become more or less common over time due to various evolutionary forces.
