The typing of human blood is determined by three alleles: A, B, and O. Alleles A and B are codominant to one another and O is recessive to both alleles, A and B.
AA/ AO – type A blood, AB – type AB blood, BB/ BO – type B blood, OO – type O blood.
A woman who is homozygous for type B blood marries a man who is heterozygous for type A.

What is the genotype ratio of their offspring?
What is the phenotype ratio of their offspring?

A female homozygous for blood type B marries a male heterozygous for blood type A, the offspring will be 75% AB and 25% Bo.

What is the genotype ratio of your offspring?

  • AB 75% BO 25%

What is the phenotypic ratio of your offspring?

  • 75% codominate AB zygotes
  • 25% B heterozygous.

What is a heterozygous being?

Homozygous and Heterozygous, in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the homozygote has two identical genes alleles, with the heterozygous beings the opposite happens, since they have two different genes alleles.

With this information, we can conclude that a female homozygous for blood type B marries a male heterozygous for blood type A, the offspring will be 75% AB and 25% Bo.
