if a woman with boood type AO has a child with a man with the blood type O what is the likely hood that their child will have the type A blood
To determine the likelihood of their child having blood type A, we need to consider the possible genotypes and their associated probability.
The woman's blood type is AO, which means she carries one allele for blood type A (A) and one allele for blood type O (O). The man's blood type is O, indicating that he has two alleles for blood type O (OO).
When considering the possible combinations of alleles that can be passed on from each parent, we get:
- Woman's possible alleles: AO (blood type A) and O (blood type O)
- Man's possible alleles: OO (blood type O) and OO (blood type O)
Since the woman has both an A and an O allele, and the man has only O alleles, the child has a 50% chance of receiving the A allele from the woman and a 100% chance of receiving an O allele from the man.
By combining the parental alleles, we can determine the possible genotypes of the child:
- AO: 50% chance (inherited from the woman)
- OO: 50% chance (inherited from the man)
Therefore, the likelihood of their child having blood type A is 50%.
