Question

A homozygous blood type male A is married to a blood type AB female. How many percent of their offspring will be:
(a) Blood type A? ________ (b) Blood type B? ________ (c) Blood type AB? _______ (d) Blood type O? ________​

Answer 1

Answer:

a) 50 % of A typ blood group

b) 0 % of typ B blood group

c ) 50 % of AB blood group

d ) 0 % of O blood group

Answer 2

BLOOD GROUPING -

• Inheritance of blood group follows Mendel's law of dominance.
• ABO blood grouping system involves four antigens A, B, O, and AB.
• A and B blood groups are dominant while the O blood group is recessive
• Blood group O is known as a universal donor as it lacks antigens and the AB blood group is known as universal acceptor as it lacks AB antibodies.
• When a homozygous male with blood group A is married to a heterozygous female with blood group AB the progeny formed will show the phenotypic ratio as:

(a) Blood group A - 50%

(b) Blood group - 0%

(c) Blood group AB - 50%

(d) Blood group B - 0%
