Question

What is the difference in number of chromosomes in sex cells compared to chromosomes in body cells? (think about the outcome of meiosis compared to mitosis)

Answer 1

Mitosis: The chromosome number remains constant (46 total chromosomes or 23 pairs of chromosomes).

Meiosis: At first the cells have the same number of chromosomes as mitosis. DNA replication occurs, giving a total of 46 chromosomes (or 23 chromosome pairs) and 92 chromatids (or 46 chromatid pairs).
