Explanation / Answer
As per the given blood types of Jim's and Leah's parents as well as Jim and Leah blood type the genotypes will be:
Jim- IAIA
Leah- IBIO
On the basis of given genotype of Jim and Leah the probable genotype of progeny will be answers will be IAIB, IAIB, IAIO, IAIO. The answers are as follows:
1. The probability that Winnie's blood type will be AB is 50% ( IAIB)
2. The probability that Winnie's blood type will be A is 50% ( IAIO)
3. The probability that Winnie's blood type will be B is 0%.
