How many chromosomes?

All body cells have TWO sets of chromosomes = diploid Sex cells (gametes/germ cells) have only one set of chromosomes = haploid That means when fertilization occurs, the new individual will have the correct number of chromosomes. How many chromosomes?.

What is Meiosis?

What is Meiosis? . MEIOSIS is the process by which reproductive cells, also called gametes , are formed. Very similar to mitosis, but cells divide 2 times , so gametes have half the number of chromosomes of body ( somatic ) cells.
