Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.

In mammals, the timing of meiosis differs greatly between males and females (Figure 2). Male germ cells, or spermatogonia, do not enter meiosis until after puberty. Even then, only limited numbers ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...

The four gametes produced in meiosis are genetically different. Independent assortment and the random nature of fertilisation lead to variation in living organisms – no two organisms are the ...
