In a large randomly mating population, allele is recessive lethal — homozygotes die before reproducing. Currently . Assuming no other forces, what is the frequency of after one generation of selection?
- A
(homozygotes are eliminated)
- B
(selection on does not change allele frequency)
- Ccheck_circle
- D
(deleterious alleles always trend toward 1/2)
Explanation
For recessive lethal, . Allele decreases each generation but slowly because heterozygotes carry it.
