Meiosis Vocabulary Gametes- cells that contain ½ the usual # of chromosomes (because 23 + 23 = 46) Egg- female gamete (1n) Sperm- male gamete (1n) Fertilization- process where sperm and egg combine to create a new cell (23 + 23 = 46) Haploid- half the usual # of chromosomes (1n)- think meiosis! Diploid- standard number of chromosomes (2n)- think mitosis!

Mitosis Meiosis Creates 4 daughter Cells that are 1n (haploid) Goes through 2 divisions (PMAT) Occurs in reproductive cells Creates 2 daughter cells that are 2n (diploid) Goes through one division (PMAT) Occurs in body cells Both undergo cell division Go through the same phases

Mitosis- number of chromosomes in each stage Meiosis- number of chromosomes in each stage 2n 2n 4n 4n 2n 2n 2n 2n 1n 1n 1n 1n
