The punnett square is attached to this.
The other possibilities are AB, BO, and AO.
All of them have 25%.
The other possibilities are AB, BO, and AO.
All of them have 25%.
Answer:
They have 1:4 chances of 0, 1:4 cahnces of AB, 1:4 chances of A, 1:4 chances of B
Explanation:
Blood has three types of alleles: A, B, 0 depending on the type of proteins in blood cells. They can have protein A, B, or not having them 0. The dominant allele will be B or A.
All types of blood are A, B, AB (co-dominance) and 0.
We all have two alleles for each gene, one comes from our mother, and one comes from our father.
If both parents are dominant, but they have a recessive child, you have both heterozygote genes to do the Punnett square.
Mother: I(A)i(0)
Father: I(B)i(0)
