Question

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

Answer 1

Answer:

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.
