Unformatted text preview: Codominance – heterozygous show both phenotype at the same time Seeing both M and N antigen independently. They are both dominance Implies an independence of allele function Neither allele is dominant over the other, thus, one cannot distinguish alleles by upper/lower case letters Codominant alleles are represented by superscripts on the symbol for the gene: L M AND l N Agglutination – the blood cells clump together Consanguineous mating – partners are blood related Complete dominance – when heterozygous offspring look like one parent but not the other Incomplete dominance – when heterozygotes show a phenotype unline that of either parent; between dominant and recessive; the phenotype of the heterozygote is an intermediate between homozygous parents In human: recessive Pleiotropy – the impact of a single gene on more than one hereditary characteristic; deal with many...
