3. There is no dominant allele, There is no recessive allele. Both alleles “blend” to result in a third phenotype.

7. Traits that are Controlled by Three or More Alleles An Individual Has a Combination of Two of These

Polygenic inheritance in people showing a cross between two mulatto parents (AaBbCc x AaBbCc). The offspring contain seven different shades of skin color based on the number of capital letters in each genotype.
