Meiosis and mitosis are both forms of cell division. However, the outcomes of these processes differ. Consider a diploid organis
m with two sexes. Select the reasons why meiosis typically produces genetic variation, whereas mitosis does not. Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment. Sister chromatids are not genetically identical as a result of crossing over during meiosis. 1n gametes produced in mitosis fuse to produce 2n cells in meiosis. Meiosis produces four genetically different haploid cells.

Explanation:
Meiosis and Mitosis are two types of cell division that occurs in living organisms. However, Mitosis produces daughter cells that are genetically identical to the parent cell while meiosis produces daughter cells that are genetically different from the parent cell. This accounts for the reason meiosis leads to genetic variation.
The production of genetically different cells by meiosis is as a result of the process of the random orientation of chromosomes during metaphase I of meiosis I. This process is called INDEPENDENT ASSORTMENT. However, crossing over occurs during prophase I of meiosis between non-sister chromatids of homologous chromosomes.
The answer is C. This is because nucleotide elongation involves the addition of a nucleotide to the 3 prime carbon of the previous nucleotide carbon ring. This involves a dehydration reaction between the phosphate group on the 5 prime carbon of the last nucleotide to the hydroxyl group of the 3 prime carbon of the previous nucleotide.
