Developmental psychology: the study of continuity and change across the life span. Prenatal stage of development ends with birth and begins when the sperm meets the egg (aww that"s you) Once that lucky sperm penetrates the egg, the egg itself releases a chemical that seals the coating and keeps the rest of the sperm from entering. Zygote: a fertilized egg that contains chromosomes from both a sperm and an egg. Each sperm cell and egg cell contain 23 chromosomes that contain genes. The 23rd chromosome can be either the x or y. Sperm cells carry the x or y. Germinal stage: 2 week period that begins at conception. Zygote begins to divide in exponential rate. Zygote will contain 23 chromosomes from each of the sex cells (46 total)
