Flashcards
Meiosis
Meiosis
A type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell.
Genetic Recombination
Genetic Recombination
The exchange of genetic material between homologous chromosomes during meiosis.
Meiosis I & II
Meiosis I & II

Study Notes
Meiosis
- Produces reproductive cells
- Duplicates DNA and creates 4 haploid cells from each diploid cell
- Two stages of cell division
Stages of Meiosis
-
Cells divide twice
-
First stage = meiosis I
-
Second stage = meiosis II
-
Allows for an exchange of genetic material between parent's chromosomes (genetic recombination)
-
Meiosis produces reproductive cells called gametes.
-
Sperm cells are produced in the testes via spermatogenesis (1 cell produces 4 sperm cells).
-
Egg cells are produced in the ovaries via oogenesis (1 cell produces 1 egg and 3 small polar bodies that degrade).
