Question

What does the magnitude of change depend on:

a) Initial population size and mutation rate
b) Genetic variation and selection pressure
c) Migration rate and genetic drift
d) Mutation rate and genetic drift

Answer 1

The magnitude of change in a population depends on genetic variation, selection pressure, mutation rate, and genetic drift.

Step-by-step explanation:

The magnitude of change in a population depends on genetic variation and selection pressure as well as mutation rate and genetic drift. Genetic variation refers to the diversity of alleles and genotypes within a population, while selection pressure determines which traits are advantageous and therefore more likely to be passed on. Mutation rate and genetic drift introduce new genetic variation into a population through random processes.
