How Does Crossing Over Increase Genetic Diversity

Question

How does crossing over increase genetic diversity?
A) Crossing over increases the different combinations of genes present in a gamete.
B) Crossing over allows specific genes to travel together on one chromosome.
C) Crossing over increases the incidence of mutations in genes.
D) Crossing over prevents the inheritance of harmful mutations.

Accepted Answer

Crossing over increases genetic diversity by allowing for different combinations of genes to be present in the gametes. During meiosis, homologous chromosomes exchange genetic material, resulting in new combinations of alleles. This can increase the genetic variability within a population.
