WebThis pattern of inheritance is described as incomplete dominance, meaning that one of the alleles appears in the phenotype in the heterozygote, but not to the exclusion of the other, which can also be seen. The allele for red flowers is incompletely dominant over the allele for white flowers.
WebBecause of dominance, it is often not possible to distinguish between a heterozygote and a homozgyote based on phenotype alone. WebThe phenotypic ratios for overdominant traits are the same as for incompletely dominant traits. Therefore, the expected phenotypic ratios among the F 2 progeny are: 1/4 Pink (A 1 A 1) 1/2 Blood Red (A 1 A 2) 1/4 Light Red (A 2 A 2) 4. Codominance: A1A1 (A antigen) is codominant to A2A2 (B antigen). The heterozygote A1A2 has both A and B antigens
