A boy has the blood group 0. What is true of the inheritance of this blood group in his case?

  1. His mother should be with AB blood group

  2. Both his parents could be heterozygous A group

  3. His father could be homozygous B group

  4. His mother could be homozygous A group
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

If the boy has blood group o, both his parents could probably be heterozygous A group, $I^AI^O$, in both the parents.

So, the correct option is 'Both his parents could be heterozygous A group'.

  2. William Harvey

  3. Malpighi

  4. None of these

A child's blood group is `O'. The parents blood groups cannot be

  1. AB and 0

  2. B and 0

  3. A and B

  4. A and A
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A child with blood group O has the genotype ii, meaning they must inherit one i allele from each parent. Parents with AB (genotype IAIB) cannot pass on an i allele, so they cannot have an O child.

A woman of blood group O' presented a baby of blood groupO' which she claimed as her child. She brought a suit against a man of 'AB' group as the father of the child. 

Which statement is correct as per your judgement

  1. The father and mother claimed are the true persons

  2. Father is true and mother is not the true person

  3. Both the parentage claims are false

  4. Mother is the true person and father claimed is not true
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A mother with blood group O (ii) can only have a child with blood group O if the father provides an i allele. A man with blood group AB (IAIB) does not possess the i allele and therefore cannot be the biological father of an O child.

In a medico-legal case of accidental interchange between two babies in a hospital, the baby of blood group A could not be rightly given to a people

  1. With both husband and wife of group 0

  2. Husband of group 0 and wife of group A

  3. Husband of group A and wife of group 0

  4. Both husband and wife of group A
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A child with blood group A (genotype IAIA or IAi) must have inherited at least one IA allele from a parent. If both parents are group O (ii), they cannot provide an IA allele, making it impossible for them to have a group A child.

Which blood group called as universal donar?

  1. $AB$
  2. $A$
  3. $B$
  4. $O$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Type O ( specifically O negative ) blood is called the universal donor type because it is compatible with any blood type. O blood group does not contain any antigen hence does not result in transfusion reactions.


So, the correct option is 'O'.

If the mother is $Rh^{-ve}$ and father is $Rh^{+ve}$, which of the following $Rh^{+ve}$ child is normally not affected?

  1. First

  2. Second

  3. Male child

  4. Female child
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rh incompatibility usually isn't a problem if it's the mother's first pregnancy because, unless there's some sort of abnormality, the fetus's blood does not normally enter the mother's circulatory system during the course of the pregnancy. However, during second child, the mother's and baby's blood can intermingle. If this happens, the mother's body recognizes the Rh protein as a foreign substance and might begin making antibodies (protein molecules in the immune system that recognize, and later work to destroy foreign substances) against the Rh proteins. Rh antibodies are harmless until the mother's second or later pregnancies. If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign, and pass into the baby's bloodstream and attack those cells. This can lead to swelling and rupture of the baby's RBCs. A baby's blood count can get dangerously low when this condition, known as a haemolytic or Rh disease of the newborn, happens.

Therefore, the correct answer is option B.

Which one of the following couple were suggested by doctors to not have more than one child?

  1. Rh$^+$ male and Rh$^-$ female
  2. Rh$^-$ male and Rh$^+$ female
  3. Rh$^+$ male and Rh$^+$ female
  4. Rh$^-$ male and Rh$^-$ female
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Rh incompatibility occurs when a Rh- negative mother is impregnated by a Rh- positive father. The result can be Rh- positive baby. In such a case, the baby’s Rh antigens will be recognized as foreign invaders. The mother’s blood cells attack the baby’s as a protective mechanism and can cause erythroblastosis fetalis. If the mother is pregnant with her first baby, Rh incompatibility is not as much of a concern. However, when the Rh- positive child is born, the mother’s body creates antibodies against the Rh factor, which will attack the blood cells if she becomes pregnant with another Rh- positive baby.
Hence, the correct answer is option A.
