The sequence of age-related changes that occur from conception to death. It"s a reasonably orderly, cumulative process that includes the biological & behavioural changes that take place as people age. Conception occurs when fertilization creates a zygote, a one-celled organism formed by the union of a sperm & an egg. Cells contains messages from parents carried on the chromosomes that lie within its nucleus. Each chromosome houses many genes, the functional units in hereditary transmission. Genes carry the details of your hereditary blueprints, which are revealed gradually throughout life. The prenatal period extends from conception to birth, usually encompassing 9 months of pregnancy. The 1st phase of prenatal development, encompassing the first 2 weeks after conception. Within 36 hours, the zygote becomes a microscopic mass of multiplying cells due to rapid cell division. This mass of cells slowly migrates along the mother"s fallopian tube to the uterine cavity.
