practice • Mom is homozygous for type A blood, while Dad heterozygous type B. What are the possible phenotypes of their children?
Practice 2. What are the PHENOTYPE % of a type AB mom crossed with a heterozygous type B dad?
3. What are phenotype % for a cross between: heterozygous type A mom and a heterozygous type B dad?
