In humans multiple alleles are involved in the inheritance of?
Pip the other answerer was correct in that multiple allelism applies to both A an D but the best example would be blood types. This is especially true for the ABO blood group. Down syndrome is non-disjunction while sex traits are usually of the complete dominance type.





Hope this helps...
Reply:The best answer is probably blood types, A, but the question is worded poorly. "Multiple" means more than 1, and technically both answers A and D involve "multiple" alleles. Standard blood types you learn in high school involve several alleles from two loci. The text book example for sickle cell involves two alleles for one locus. The question was likely meant to read "multiple loci," which is why I think A is the best answer.
Reply:the question isnt very specific to be honest o.o...


Alleles can determine anything from sex to genetic disorder to genetic traits like blonde hair blue eyes
