A Mendelian trait is controlled by one gene and features a one-two-one genotype ratio and a three-one phenotype ratio. These ratios exist because these genes possess two alleles. More »

An intermediate phenotype describes an organism that displays a blend of the phenotypic traits that its parents expressed. If a red flower cross-pollinates a white flower, and the resulting offspring are pink, the offspr... More »
