What will be the blood groups of the children of following matings?
`I^A I^B xx I^B I^B`

What will be possible blood group in children from the parents with B and AB blood groups ?

The gene that controls the ABO blood group system in human beings has three alleles -I^(A),I^(B) and i. A child has blood group O. His father has blood group A and mother has blood group B. Genotypes of other off springs can be: i. I^(B)I^(B) ii. I^(A)i iii. I^(B)i iv. I^(A)I^(B) v. ii

The genotypes of husband and wife are I^(A)I^(B) and I^(A)i . Among the blood groups of their children how many different genotypes and phenotypes are possible

What are the possible blood groups likely to be inherited by children born to a group A mother and a group B father ? Explain your reasoning.

The gene that controls the ABO blood group system in human beings has three alleles- I^(A), I^(B) and i. A child has blood group O. His father has blood group A and mother has blood group (B) Genotypes of other off springs can be: (I) I^(B)I^(B) (II) I^(A)i (III) I^(B)i (IV) I^(A)I^(B) (V) ii

How many different blood groups are possible in a diploid species with ABCD blood grouping system involving I^(A) , I^(B) , I^( C) and I^(O) alleles ( I^(O) is recessive and others are co-dominant )

(a) List the three different allelic forms of gene 'I' in humans. Explain the different phenotypic expressions, controlled by these three forms. (b) A woman with blood group 'A marries a man with blood group 'O'. Discuss the possibilities of the inheritance of the blood groups in the following starting with "yes" or "no" for each: (i) They produce children with blood group "A" only. (ii) They produce children some with "O" blood group and some with "A" blood group.

The following table shows the blood groups of 60 students of a class : |{:("Blood groups A B O AB"),("Number of students 16 12 23 9"):}| One student of the class is chosen at random. What is the probability that the chosen student has blood group? "(i) O (ii) AB (iii) A (iv) B"

Solve the following cryptarithms: (i) A B x6\\ B B B

The genotypes of a husband and wife are I^(A)I^(B) and I^(A)i . Among the blood types of their children, how many different genotypes and phenotypes are possible?
