Meiosis The creation of Gametes

Creation of Gametes l Interphase ¡Diploid Cell ¡Cell Resting ¡Toward late interphase nucleus becomes

Creation of Gametes l Interphase ¡Diploid Cell ¡Cell Resting ¡Toward late interphase nucleus becomes grainy duplicating of DNA

Meiosis— 1 st Division l Prophase I ¡Nuclear membrane disappears ¡Chromosomes form with copies

Meiosis— 1 st Division l Prophase I ¡Nuclear membrane disappears ¡Chromosomes form with copies ¡Chromosomes pair

Meiosis— 1 st Division l Metaphase I ¡Lining up of pairs of chromosomes at

Meiosis— 1 st Division l Metaphase I ¡Lining up of pairs of chromosomes at center of cell

Meiosis— 1 st Division l Anaphase I ¡Chromosome pairs split

Daughter Cells l Results in 4 haploid gametes l End results differ in males

Daughter Cells l Results in 4 haploid gametes l End results differ in males and females

Spermatogenesis—Male Meiosis Spermatogenesis creates 4 haploid sperm from 1 body cell

Spermatogenesis—Male Meiosis Spermatogenesis creates 4 haploid sperm from 1 body cell

Oogenesis—Female Meiosis Will not become eggs that can be fertilized— will degenerate and be

Oogenesis—Female Meiosis Will not become eggs that can be fertilized— will degenerate and be reabsorbed by the body 1 body cell becomes 1 haploid egg and 3 haploid polar bodies
