Meiosis involves a diploid cell replicating its chromosomes, dividing twice, and resulting in four haploid cells, each with a single set of chromosomes.
Meiosis starts with a diploid cell, replicates chromosomes, divides into two haploid cells with paired chromosomes, and then divides again to form four haploid cells with single sets of chromosomes.
| Front | Meiosis stages (1-6) |
|---|---|
| Back | 1-cell with two pairs of chromomes (diploid cell) 2-each chromosome replicates itself 3-chromosomes part company and move to opposite poles 4-cell divides for the first time, there's now two, one pair of chromosomes in each. 5-copies now seperate cell, second cell divison occurs 6-four haploid cells each with half the number of chromosomes of the parent cell. |
