Why is mitosis incompatible with the production of sperm and oocytes
Naily [24]

Answer:

Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells

Explanation:

Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.
