Mother’s Blood Type |
AB |
|
Father’s Blood Type |
B |
|
Child’s Blood type |
A/B/AB |
Alleles for blood types are A, B or O.
A and B are dominant over O.
Mother (AB+) X Father (B+) (here alleles could be both B or B and O. We have considered here alleles as B and O)
IA IB X IB IO
IAIB IAIO IBIB IBIO
Hence, there are approximately 25% chances that the offspring will have the blood group A+.
