A woman with blood group O married a man with AB blood group. Show the possible blood groups ofthe progeny. List the alleles involved in this inheritance. What is this type of inheritance called?

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.

Alleles involved: \(I^A,\ I^B,\ I^O\)

Type of inheritance: Multiple allelism with codominance.
