AP Biology Meiosis Essay

Meiosis is the process in sexually reproducing organisms where cells divide. The cells produced during meiosis have half the chromosome number as the original cell. There are two cell divisions in meiosis, meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only one set of chromosomes, which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in …

…unites with the haploid from the father to produce a diploid zygote. The gamete from the mother is one of 8 million and the gamete from the father is one of 8 million. Independent assortment occurs during prophase ll of meiosis l. The Law of Segregation is Mendel's first law, which states that allele pairs separate during gamete formation, and then randomly re-form as pairs during the fusion of gametes at fertilization. This occurs during anaphase l.
