Question

Accepted Answer

∻Answer∻ ⚹ No, James' claim cannot be true. ⚹ ∻Solution∻ ‖ a ⋮ Blood type inheritance: Blood types are inherited from parents, with each parent contributing one allele to their offspring. ‖ ‖ b ⋮ Blood type O: Individuals with blood type O have two O alleles ($OO$). ‖ ‖ c ⋮ Blood type A: Individuals with blood type A can have two A alleles ($AA$) or one A and one O allele ($AO$). ‖ ‖ d ⋮ Blood type AB: Individuals with blood type AB have one A allele and one B allele ($AB$). ‖ ‖ e ⋮ Paternity exclusion: Since James has blood type O ($OO$), he can only pass on an O allele to his offspring. Luke has blood type AB, which means he must have received an A allele from one parent and a B allele from the other. ‖ ‖ f ⋮ Conclusion: Because James can only contribute an O allele and Luke has an AB blood type, James cannot be the biological father of Luke. ‖ ∻Key Concept∻ ⚹ Blood type inheritance patterns ⚹ ∻Explanation∻ ⚹ James, with blood type O, cannot be the father of Luke, who has blood type AB, because Luke must have inherited an A allele and a B allele from his parents, and James can only pass on an O allele.◊What type of inheritance pattern is being portrayed in this blood type scenario?⍭ Generate me a similar question◊⚹
