WebHeredity is the passing on of traits from parents to offspring. Most plants and animals have two of every kind of gene , one from their mother and one from their father. Only one gene from each parent is passed to each offspring for a particular trait. There are different forms of a gene that are referred to as alleles . WebThus, a heritability of .80 (80%) suggests that genes contribute more to trait variance in the population than does a heritability of 40%. However, heritability provides no information regarding how many genes are involved, how strong the effect of any given gene is, or how easy it will be to identify contributing genes. photo of forest trees
