10. A seemingly crazy man showed up at Jalen's doorstep, claiming to be his long lost twin brother. The man
persisted in his claim, and to prove or disprove this Jalen requested the crazy man's blood type card. The man
was type AB. Jalen knew his blood type is O and that his mother and father's blood type is both type A blood.
Explain how this information proves that the crazy man is NOT his brother.

Final answer:

Parents with blood types A and B cannot have a child with Type O blood due to genetic inheritance.


Explanation:

Person with Type O blood cannot be a legitimate child of parents with blood Type A and B. The reason is that the genotype for Type O blood is ii, which means both alleles are O. Therefore, to have a child with Type O blood, both parents must pass down an O allele. Since parents with A and B blood types do not carry the O allele, they cannot have a child with Type O blood.
