Question

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:

Answer 1

The three alleles that exist for human blood types are A, B, and O. These alleles are denoted as IA, IB, and i respectively. IA and IB are codominant alleles that produce antigens A and B on the surface of the red blood cells while ii is the recessive allele for type O. Humans are diploid; every individual carries only two alleles.For the given scenario, there are six possible blood group genotypes. These are as follows:IAIA or IAi: Blood group AIBIB or IBi: Blood group BIAIB: Blood group ABii: Blood group OTherefore, the six possible blood group genotypes are IAIA, IAi, IBIB, IBi, IAIB, and ii. These combinations are the only possible genotype combinations that could exist for human blood types.
