Key concepts
3 concepts
- 1
Meiosis is a process that contributes to genetic variety by creating sperm and egg cells (also known as gametes).
- 2
During prophase I of meiosis, homologous chromosomes can exchange genetic information through a process called crossing over, leading to recombinant chromosomes.
- 3
In meiosis II, the chromosomes line up in the middle of the cell in metaphase II and then the chromatids are pulled away in anaphase II.
