a homozygous dominant individual (AA)is crossed with an individual that is heterozygous for the same trait (Aa). What are the possible genotypes of the offspring and what percentage of the offspring is likely to sho the dominant phenotype?
100%
what is codominance?
an inheritance relationship in which neither of the twoalleles of the same gene totally mask the other

266/1064
What is Incomplete Dominance?
an inheritance relationship that occurs when both alleles influence the phenotype
