The two processes that increase genetic variation in sexually reproducing organisms are:
a. **Crossing over** - This process occurs during meiosis when homologous chromosomes exchange genetic material, leading to new combinations of alleles.
c. **Mutation** - This is a change in the DNA sequence that can create new alleles, contributing to genetic diversity in a population.
While independent assortment and segregation also play roles in genetic variation, crossing over and mutation are the key processes that specifically enhance genetic diversity.
