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

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

Parents with blood group O will have children with blood groups

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

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 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

(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.

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 )

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"

The blood groups of 30 students of class IX are recorded as follows: A B O O AB O A O B A O B A O O A AB O A A O O AB B A O B A B O A student is selected at random from the class from blood donation. Find the probability that the blood group of the student chosen is: (i) A (ii) B (iii) AB (iv) O

The following table shows the blood groups of 40 students of a class. One student of the class is chosen at random . What is the probability that the chosen student has blood group (i) O ? (ii) AB ?
