Amy Rice BSC 2010L 11/13/08 Homework Assignment #9 Meiosis and Genetics (Lab 9) A. Meiosis Questions 1 . In animals, meiosis takes place in the gonads: the testes in males, and the ovaries in females. 2. In females, meiosis, called oogenesis, begins while still an infant, but it halted in Prophase I until the female enters puberty. After puberty, one cell continues meiosis until meiosis I is completed. Meiosis II does not occur until the haploid cell is fertilized. When cytokinesis occurs, it is uneven, creating one large call and three small ones. Only the large haploid cell is functional; the other three smaller cells, called polar bodies, are not functional and eventually disintegrate. Meiosis in males, called spermatogenesis, begins when the male enters puberty and continues until death. Unlike oogenesis, all four of the cells produced from one diploid cell during spermatogenesis are the same size and all are functional. 3.
