Meiosis, Overview
Captions available
The idea
Meiosis is the nuclear division producing four haploid daughter cells from one diploid parent cell, across two successive divisions after one round of DNA replication.
In practice
A diploid germ cell entering meiosis exits as four haploid gametes, each carrying one member of every homologous pair.
Where people slip
Meiosis halves chromosome number once, across two divisions, not once per division.
