NEET BIOLOGY

Detailed explanation-1: -A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

Detailed explanation-2: -Usually, an AB parent and an A parent can only have children who are Type A or Type B. One exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.

Detailed explanation-3: -Answer and Explanation: If a AB blood type woman and a O blood type man have a child, then their children’s probable blood type will be either A or B blood type. No O or AB blood type would be possible.

Detailed explanation-4: -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-5: -Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.
