Paland and Lynch showed that sexual populations have fewer deleterious mutations than asexual populations. These results support the hypothesis that
A. asexual reproduction is associated with lower genetic diversity, resulting in the accumulation of highly deleterious mutations.
B. sexual reproduction prevents fertilization with gametes carrying alleles with deleterious alleles.
C. sexual reproduction produces fewer random mutations than asexual reproduction.
D. sexual strains are associated with higher genetic diversity and thus accumulate more beneficial mutations than asexual strains.
E. in sexual reproduction, the reassorting of alleles allows for the elimination of more detrimental alleles than in asexual reproduction.
