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.

Explanation

Child blood group is O, and O has the genotype `I^@ I^@` Hence if father has blood group A and mother has blood group B, then the possible genotype of the parents will be `I^A I^@` and `I^B I^@` respectively.

Genotypes of the off springs
`I^A I^B`- AB blood group
`I^A I^O` -A blood group
`I^B I^O`- B blood group
`I^O I^O`- O blood group
