Work out a cross upto F1 generation between a mother with blood group A (homozygous) and a father with blood group B (Homozygous). Explain the patten of inheritance exhibited.

A man with blood group A marries a woman with blood group B. They have a son with blood group AB and a daughter with blood group O. Work out a cross and show the possibility of such an inheritance. As the son has blood group AB and the daughter has blood group O the possible genotype of the father is IA i and of the mother is IB i.

Find out the inheritance pattern in blood groups of human beings.

A child has blood group O. If the father has blood group A and mother blood group B, work out the genotypes of the parents and the possible genotypes of the other offsprings.

Motherand father of a personwith'O' blood group .have 'A' and 'B' blood group respectively. What would be the genotype of both mother and father?

What is the cross between the progeny of F1 and the homozygous recessive parent called? How is it useful?

Conduct a cross between a homozygous pea plant for purple axial flowers and a homozygous pea plant for white terminal flowers: Find out the types of progeny in F_2 and the proportion in which they occur.

A homozygous pea plant with green pods was crossed with a homozygous pea plant with yellow pods. F_1 produced 883 plants with green pods and 220 plants with yellow pods. State the generalization proposed by Mendel on the basis of the above statement.

Using a Punnet square, work out the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a hetrozygous male for a single locus.

A cross between a homozygous pea plant with a dominant character and a homozygous pea plant with a recessive character showed F_1 hybrids expressing the dominant character only. Which law of Mendel's applicable to the above statement?
