WebOct 27, 2024 · There are 23 chromosome pairs in a single human cell, but imagining 23 different colored pairs of socks is quite confusing, so it is easier to stick to a single chromosome (or one pair of stripey socks). When replication occurs (before either mitosis or meiosis) and the cell enters the S-phase, these 2 socks are each given an exact twin.
