KEY CONCEPT Phenotype is affected by many different factors. In (3.)incomplete dominance , (AKA- intermediate dominance) neither allele is completely dominant nor completely recessive. Heterozygous phenotype is intermediate between the two homozygous phenotypes

4 blood types3 alleles
(6)Polygenic -many genes may interact to produce one trait. The genes may be on the same or on a different chromosome.Result in a wide rangeof variation.Ex. Hair color, height eye color
Ex.The sex of sea turtles depends on both genes and the environment-(temperature of the nest)
