Web1. Law of Co - dominance: In co-dominance heterozygotes express the phenotype of both parents e.g. ABO blood groups and sickle cell anemia. In co-dominance, there is an independence of allele function. Neither allele is dominant or partially dominant over the other. 2. Law of incomplete dominance: One allele is not completely dominant to another.

WebMendel found that paired pea traits were either dominant or recessive.When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel counted the number of second-generation (F2) progeny with dominant … WebCodominance Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote.
