When offspring produced by sexual reproduction move into different environments, new species sometimes
emerge over time. Which characteristic of sexual reproduction allows this result to occur?
A speed with which offspring are produced
B diversity of the offspring produced
Csize of the offspring produced
D number of offspring produced

Option B) diversity of the offspring produced

Explanation:

Since sexual reproduction involves the fusion of male and female gametes formed by meiosis, and meiosis involves the formation of gametes that that undergone crossing over or exchange of genetic material between sister chromatids, hence, the resulting sex cells are usually different in genetic composition from the individual parents.

Thus, the crossing over of genetic material in sexual reproduction allows new species to emerge over time.

i think the answer would be d

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
