# 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. - Biology (Theory)

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.

#### Solution

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.
