Question

population genetics is the study of the:
genetic makeup of populations and how it changes over time.
total collection of alleles in a population.
relative proportion of an allele in a population.
allele frequency in a population.

Explanation:

Population genetics focuses on the genetic composition of groups (populations) and the evolutionary processes that alter this composition over generations. The other options describe specific components (e.g., allele collection, allele proportion/frequency) rather than the broad scope of the field.

Answer:

genetic makeup of populations and how it changes over time.
