Chromosomes form DNA takes to get passed from parent to child. Humans have 23 pairs of chromosomes. Heredity The passing of traits from parents to offspring Blending inheritance The discredited theory that inheritance of traits from two parents produces offspring with characteristics that are intermediate between those of the parents. Gene section of DNA in a specific location on the chromosome that contains information that determines that trait. Polygenic trait trait controlled by ...
