Answer:
D
Explanation:
Cells are living things therefore, nonlivng objects do not have cells
Since the trait is dominant, it is possible for his parents to be heterozygous (Bb). So they have the trait but they have a gene they can pass on with out it. If both of his parents Bb then he could’ve gotten both recessive and therefore not receive the trait
This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition
True??? I think u don’t need to put the answer I gave u but it’s just my thought
Crossing over, or recombination is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
