Document Summary

In genetics, we can have simple/complete dominance, where the phenotype of the heterozygote cannot be distinguished from the phenotype of the homozygous dominants. Or, we can have incomplete dominance/semi-dominance/partial dominance, where the phenotype of the heterozygote can be distinguished from the phenotype of both homozygotes. Some genes have many alleles: some of these alleles are common, while others are rare. Some alleles are associated with certain breeds of varieties of plants and animals. The frequency of a particular allele varies from population to population. Added sugars serve as antigens on the surface of rbcs. These alleles are codominant: both alleles are fully expressed in the heterozygote, two distinct proteins are made. In this case, two different transferases are made. Individuals with type ab blood are universal recipients othey can take type a, o, or b. But, they can only give blood to other ab individuals. Blood typing used to be used as a form of paternity testing
