Topic: Hardy-Weinberg principle
Introduction:
Hardy-Weinberg equilibrium states that genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
Step-by-step explanation:
Consider a population. If this population is in Hardy-Weinberg equilibrium for a gene, this means that it is not evolving, and allele frequencies will stay the same across generations. Now, there are five basic Hardy-Weinberg assumptions:
1. No mutation,
2. Random mating,
3. No gene flow
4. Infinite population size
5. No natural selection.
Then, if those assumptions are not met for a gene, the population may evolve for that gene.
Then, we can conclude that the correct answer is:
Answer:
A. There is no random mating
