Document Summary

Phenotype a person"s observable or measureable characteristics. Genotype the genes that a person inherits. Mitosis the process in which a cell duplicates its chromosomes and then divides into two genetically identical daughter cells. Meiosis- the process in germ cell divides, producing gametes (sperm or ova) that each contain half of the parent cell"s original complement of chromosomes; in humans, the products of meiosis contain 23 chromosomes. Independent assortment the principle stating that each pair of chromosomes segregates independently of all other chromosome pairs during meiosis. Monozygotic twins identical twins ; develop from a single zygote that later divides to form two genetically identical individuals. Dizygotic twins fraternal twins ; twins that result from the mother releasing two ova at roughly the same time and each are fertilized by a different sperm, producing two zygotes that are genetically different. Autosomes the 22 pairs of human chromosomes that are identical in males and females.
