You collect the following data on genotypes for a sunflower population:

AA: 15, AB: 70, BB: 15 (so there is an A and a B allele).

Based on Hardy-Weinberg predictions you expected the following numbers:

AA: 25, AB: 50, BB: 25.

Which of the following is a plausible explanation for the deviation?

a) Balancing selection

b) Negative frequency-dependent selection

c) Inbreeding

d) Genetic drift

C. Inbreeding

Explanation:

Breeding of organisms which are closely related genetically (ancestry).

Inbreeding is useful in the retention of desirable characteristic (which we want to retain) or the elimination of undesirable one (which we do not want to retain).

Indreeding often results in decreased vigour, size, and fertility of the offspring.
