Dr. Lala .A.



Imagine you were in a show and you had to answer 5 questions correctly to win a million.
Let’s Take This Quiz To See How Much We May Win.

1. How Many Blood Types Are There?
a) 3 b) 4 c) 5 d) 6


2. What is Your Blood Type?
a) A b) B c) AB d) O


3) How many blood genotypes are there?
a) 3 b) 4 c) 5 d) 6


4) What is your Rhesus type?
a) Rh+ve b) Rh-ve


5) Could a man with type B blood and a woman with type AB produce a child with type O blood?
a) Possible b) Not possible


6) If the mother of a child is blood type O+ and the child is A-, what blood type would the father be? The father could be: (a) A+, A-, or O- (b) A+, A -, AB+, or AB- (c) B+, B-, or O-


7) Which of the following is not a blood cell?
a) White blood cell. b) Red blood cell. c) Pink blood cell d) Platelet





1) b – There are 4 blood types; A, B, AB, O
People AB blood group are said to be a universal recipients of other blood groups while people with O type of blood group are universal donors.

2) You should know that, if you don’t, go to your doctor and ask for a blood test.


3) d – 6
Blood type Possible genotypes





4) You should also know that, otherwise ask your doctor for a test.


5) b – Not possible
The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Therefore, the child could not possibly be of blood type O. The children of a man with type B blood and a woman with type AB blood could be type A, type B, and type AB, but not type O.


6) Blood types
The father has to be the source of the A allele of a child with blood type A, when the mother is of blood type O. The father could be type A or type AB. The types that can be ruled out for the father are type O and type B.
Mother’s Possible Genotype – OO
Child’s Possible Genotypes – AO
Father’s Possible Genotypes – AA, AB
Rh factor
The Rh factor information doesn’t discriminate potential fathers of the child. Even though the child is Rh-, it is not necessary that either parent be Rh-. The father of the child could be either Rh+ (heterozygous with one Rh+ allele and one Rh- allele) or Rh- (homozygous with two recessive Rh- alleles. )
When the mother is Rh- and the father is Rh+ (heterozygous with one Rh+ allele and one Rh- allele), there is a 50% probability for an Rh+ child and a 50% probability for an Rh- child. When the mother is Rh- and the father is Rh-, then all children will be Rh-

7) c – There are three blood cells which are; Red blood cells help to carry oxygen from the lungs to the rest of the body and returns carbondioxide from the body to the lungs from which it can be exhaled. White blood cells protect the body from infection. Platelets assist in blood clotting and prevent excessive bleeding from injuries.
