The person with type AB blood has a heterozygous Rh factor.
- Half the gametes have Rh factor (+) and the other half are negative for Rh factor (-)
- Half the gametes have IA and the other half have IB
- The possible gamete combinations are IA+, IA-, IB+, IB-
The person with heterozygous type A blood is negative for Rh factor
- All gametes are negative for Rh factor (-)
- Half the gametes have IA and the other half have IO
- The possible gametes are IA-, IO-
The genotype ratio is 1:1:1:1:1:1:1:1
