Example 1: Mother is heterozygous type A and the father is type O. What are the genotype ratios and phenotypic ratios?
To determine the genotype and phenotypic ratios, we first need to determine the possible genotypes of the offspring.
The mother is heterozygous type A (genotype: AA or AO) and the father is type O (genotype: OO).
Possible genotypes of the offspring:
- AO (type A) from the mother
- OO (type O) from the father
Genotype ratios:
- AO (type A) = 1
- OO (type O) = 1
Phenotypic ratios:
- 100% of the offspring will have type A blood.
