Explanation:
Detailed explanation-1: -Answer and Explanation: A man with type O blood would not be able to produce a child with type AB blood regardless of the mothers blood type. This is because type O blood is recessive and these individuals have two O alleles so the only allele they would be able to pass to a child would be “O".
Detailed explanation-2: -But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is even more unlikely). In fact, a child can get almost any kind of blood type if you consider the rule-breaking exceptions.
