Question

Please answer quick please

A particular allele in mice is lethal in homozygotes. Heterozygotes, however, develop normally. Why does this allele remain in the population?

A) Homozygous mice pass the allele to their offspring

B) The recessive allele is masked in heterozygotes

C) Natural selection selects for the homozygous individual with normal alleles

D) Natural selection selects against the heterozygous individual

Answer 1

B

Step-by-step explanation:

In a heterozygous mouse they have both the dominant and recessive gene which means although the dominant gene may be the one presented, the recessive gene is still there and it is able to be passed down.
