Inbreeding

Question

Inbreeding
A) increases the frequency of heterozygotes by 2pqF.
B) decreases the frequency of homozygotes by pqF.
C) increases the chances of deleterious genes combining.
D) increases the total genetic variation of the population.
E) none of the above

Accepted Answer

Inbreeding increases the chances of deleterious genes combining because it increases the probability that both alleles at a locus are identical by descent, leading to an increase in homozygosity and the expression of recessive deleterious alleles.
