Heredity is the passing of phenotypic traits from parents to their offspring, either through asexual reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited by individuals can accumulate and cause some species to evolve through the natural selection of specific phenotype traits.
The inheritance of biological characteristics is determined by individual units known as genes. They are passed from parent to offspring. In cases in which two or more alleles of the gene for a single trait exist, some forms of the gene may be dominant or recessive. In most sexually reproducing organisms, each adult has two copies of each gene- one from each parent. These are segregated from each other when gametes are formed.
