To determine the possible blood types of the children from a man with blood type AB and a woman with blood type O, we can start by looking at the possible alleles each parent can pass on.
- The father with blood type AB has the genotype IAIB (where IA represents the A allele and IB represents the B allele).
- The mother with blood type O has the genotype ii (where the lowercase i represents the O allele).
When these two parents have children, the possible combinations of alleles can be determined by creating a Punnett square:
| | IA | IB | |-------|-------|-------| | i | IAi | IBi | | i | IAi | IBi |
The offspring can inherit the following genotypes:
- IAi (Blood type A)
- IBi (Blood type B)
Now, since both IAi and IBi result in distinct phenotypes, we can summarize the expected phenotypes of their children:
- 50% will have blood type A (genotype IAi).
- 50% will have blood type B (genotype IBi).
- There will be no children with blood type O or AB.
In summary:
- 50% of the children can be expected to have blood type A.
- 50% of the children can be expected to have blood type B.
Therefore, the expected phenotype percentages are:
- 50% Blood Type A
- 50% Blood Type B
