Mendel and Heredity
... Why are some physical traits more common than others? An organism’s physical traits are determined by its genetic makeup. Most organisms inherit two versions of a gene for each physical trait. Sometimes, one gene is “dominant” over another “recessive” gene. When and organism inherits two dominant ge ...
