genotype, the dominate trait is evident while the recessive gene is masked. This is called complete dominance which makes the offspring a carrier of the recessive gene. However, sometimes there is a p ... which the dominant phenotype is not fully expressed in the heterozygote. This is called incomplete dominance, where the resulting phenotype is an intermediate between the homozygous dominant and homo ...
