Document Summary

Genotype: genetic endowment that an individual inherits. Phenotype: the ways in which a person s genotype is expressed in observable/measurable characteristics. Conception: the moment of fertilization, when a sperm penetrates an ovum, forming a zygote. When a sperm cell penetrates the lining of the ovum, a biochemical reaction repels other sperm. Genes on each chromosome also function as pairs two members of each gene pair being located at the same sites on their corresponding chromosomes. Growth of the zygote & production of body cells. By the time a child is born, they have billions of cells. Mitosis continues through life, generating new cells that enable growth, and replacing old ones that are damaged. Every new cell contains an exact copy of the 46 chromosomes we inherited at conception. Germ cells serve one special hereditary function to produce gametes (sperm in male, ova in females) Different type of cell reproduction than mitosis.
