how many possible genotypes are there for the AB+phenotype?

Question

Accepted Answer

∻Answer∻ ⚹ There are six possible genotypes for the AB+ phenotype. ⚹ ∻Solution∻ ‖ a ⋮ Blood type is determined by the ABO system and the Rh system. ‖ ‖ b ⋮ The ABO system has three alleles: $ I^A $, $ I^B $, and $ i $. ‖ ‖ c ⋮ The Rh system is determined by the presence (Rh+) or absence (Rh-) of the Rh factor. ‖ ‖ d ⋮ For the AB+ phenotype, the Rh factor must be present, and the individual must have at least one $ I^A $ allele and one $ I^B $ allele. ‖ ‖ e ⋮ The possible genotypes for the ABO system are $ I^A I^A $, $ I^A i $, $ I^B I^B $, $ I^B i $, and $ I^A I^B $. ‖ ‖ f ⋮ Since the Rh+ phenotype can be homozygous dominant (Rh+ Rh+) or heterozygous (Rh+ Rh-), each ABO genotype can be combined with these two Rh genotypes. ‖ ‖ g ⋮ The genotypes for AB+ phenotype are $ I^A I^B $ Rh+ Rh+, $ I^A I^B $ Rh+ Rh-, $ I^A I^A $ Rh+ Rh+, $ I^A I^A $ Rh+ Rh-, $ I^B I^B $ Rh+ Rh+, and $ I^B I^B $ Rh+ Rh-. ‖ ∻Key Concept∻ ⚹ The AB+ blood type is determined by the combination of ABO alleles and the Rh factor. ⚹ ∻Explanation∻ ⚹ The AB+ phenotype requires the presence of both A and B antigens and the Rh factor, leading to six possible genotypes when considering the ABO alleles and Rh factor combinations. ⚹◊How many alleles are involved in determining the ABO blood group phenotype?⍭ Generate me a similar question◊
