Meiosis
Sexual Reproduction
Meiosis | An example of sexual reproduction |
Homologous Pairs | A pair of chromosomes (one from mom and one from dad) that are the same shape, same height, and have genes in the same place |
Purpose of Meiosis | To create gametes |
Gametes | Sex cells |
Female gamete | Egg |
Male gamete | Sperm |
Cross over | When chromosomes exchange genetic material, it breaks off and reattaches to the other chromosome |
End Result of Meiosis | 4 haploid cells (23 chromosomes) that are all different |
Haploid | Half the number of chromosomes |
Germ cells | Cells that reproduce using meiosis |
Purpose of Mitosis | Growth and repair of damaged tissues |
End result of Mitosis | 2 cells that look genetically identical |
