Question

A woman with blood group O married a man with blood group AB shows the possible blood groups of the progeny. List the alleles involved in this inheritance.

Answer 1

Women with Blood group O married a man with Blood group AB

Hence the genotype of parents are

Mother - `I^OI^O`

Father – `I^A I^B`

Using the punnet square method, the possible blood groups in the progeny are as follows:

	`I^O`	`I^O`
`I^A`	`I^A I^O`	`I^A I^O
`I^B`	`I^BI^O`	`I^BI^O`

Hence the possible genotype are – `I^A I^O` and `I^BI^O`

possible phenotype are – Blood group A and Blood group B.
