Question

part a the process of meiosis produces gametes, egg or sperm, that participate in sexual reproduction. replicated during both meiosis and mitosis, we can see that meiosis enhances genetic variation rather than genetic sameness because part b remember, sexual reproduction includes the union of a sperm and an egg during fertilization. consider the gametes produced via meiosis in the image; imagine that they are all sperm on the way to fertilize an egg. what is the best explanation as to how this enhances genetic variation? a during sexual reproduction, mating is random and this enhances genetic variation. b because each sperm varies slightly, the offspring that result will all vary as well. c the union of sperm and egg to restore the diploid chromosome number and random assortment of homologous chromosomes and crossing - over during meiosis produce variation. d both random assortment of homologous chromosomes and crossing - over during meiosis produce variation.

Explanation:

In sexual reproduction, meiosis produces gametes (sperm or egg). Random mating during fertilization and processes like random assortment of homologous chromosomes in meiosis contribute to genetic variation. Each sperm is slightly different, and the union of sperm and egg is random, leading to varied offspring.

Answer:

A. During sexual reproduction, mating is random and this enhances genetic variation.
B. Because each sperm varies slightly, the offspring that result will all vary as well.
C. The union of sperm and egg to restore the diploid chromosome number enhances genetic variation.
D. Both random assortment of homologous chromosomes and crossing - over enhance genetic variation.
