Document Summary
During the course of development, the genotype interacts with the. Ovum: the female germ cell, or egg, it is about 90,000 times more. Phenotype: created by the interaction of a person"s genotype, Genotype: is the particular set of genes that a person inherits (cid:1) from their parents. The sperm: the smallest of all human cells, in the shape of a head, (cid:1) where heredity is a whip-like tail, which it uses to propel itself through the womens reproductive system. They carry genetic information that help direct development (cid:1) Crossing-over: the process by which equivalent sections of homologous chromosomes switch places randomly, shuffling the genetic information each carries (cid:1) duplicating its chromosomes so that the new, daughter cells contains the usual 46 chromosomes. Thus the zygote divides and continues to divide, each time producing new cells that have the full complement of 46 chromosomes, and gradually becomes a multi-cellular organism (cid:1)
