Question #58ad7
2 Answers
You set up a Punnett square using the parent's genotypes. The Punnett square will give you the offspring's genotypes. Then you will use these genotyes to interpret the offspring's phenotypes.
Explanation:
The mother has two different alleles, A and B. The man has two identical alleles, O and O.
The offspring will inherit an O allele from the Dad no matter which allele it gets from the mother. From the mother it can inherit either an A or a B. Hence the possible genotypes for the offspring are AO and BO.
All the children of this match will be either
AO
BO
Explanation:
Mother x Father
Each child inherits one allele from the mother -- either the gene for type A blood, or the gene for type B blood.
A _
B _
Each child also inherits one allele from the father -- but in his case, both his alleles are the same, so they all get one gene for type O blood from him.
That means that the only two outcomes for the children of this match are either:
AO
BO
