Question

why does sexual reproduction result in more genetic variation in a species?
a. it increases the chromosome number.
b. it produces haploid organisms.
c. it mixes the chromosomes of the two parents.
d. it increases the number of genes in each organism.

Explanation:

Sexual reproduction involves the combination of genetic material from two parents. Gametes (sperm and egg) are formed through meiosis, which shuffles genetic material via processes like crossing - over and independent assortment. When gametes fuse during fertilization, the chromosomes of the two parents are mixed, leading to new combinations of genes and thus more genetic variation.

Answer:

C. It mixes the chromosomes of the two parents.
