In a large population of sea stars, half of the individuals possess the red allele
and half possess the purple allele. Those with the purple allele are better able
to hide from predators. Therefore, more of them will survive and reproduce.
Which of the following requirements for the Hardy-Weinberg equilibrium is not
being met?
O
A. The population must be infinitely large.
O
B. Each allele must be equally beneficial.
O
C. No immigration can occur.
O
D. No mutation can occur.​

Answer:

B. Each allele must be equally beneficial.

Explanation:

There are five main requirements to achieve Hardy-Weinberg equilibrium:

  1. No mutation
  2. No migration or gene flow
  3. Very large population
  4. Random mating
  5. No natural selection

The red-purple allele difference has to do with #5, no natural selection. This difference in alleles "Therefore, more of them will survive and reproduce" indicates natural selection, and hence evolution, may occur, which cannot happen in Hardy-Weinberg.
