For practice, let's work with blood groups. Three alleles exist for human blood types. They were not numbered, but instead marked with the letters for A, B and O. The labeling convention is : IA, IB, and Ii. IA and IB are codominant alleles, whereas Ii is the recessive allele for type O. Humans are diploid; every individual carries only two alleles. For the following question list all 6 possible Blood group genotypes. The first has been done for you below: IAIA Can you please EXPLAiIN how you got the answer as if you were explaining to a 1st grader because I have no idea how you get the answer? is there a punnette square to this? thank you! .
