When do organisms complete meiosis?

Answer 1

Meiosis is the process of making gametes (sex cells), so depending on what you mean by your question, either of the following may be correct:

1.) Meiosis will be complete after the individual no longer makes gametes. In humans, females complete meiosis even before they are born because they create all the eggs they will ever have during gestation. In males, this is an ongoing process.

2.) Meiosis may also be considered complete after the products are finished. In humans, females produce 1 egg and 3 polar bodies. In males, 4 sperm are produced.

Answer 2

Organisms complete meiosis during the formation of gametes, which are specialized cells involved in sexual reproduction. In humans, meiosis occurs during the formation of eggs in females and sperm in males.
