No, it is impossible to get an A-type from two O-types.
it is possible but the child can be a positive
No.
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
If both parents have A positive blood, their child would most likely also have A positive blood. This is because the child inherits one blood type allele from each parent, and A positive is dominant, so it is highly probable for the child to have the same blood type as the parents.
yes they can
No, two parents who are both blood type O positive cannot have a child who is blood type A positive. Blood type inheritance follows specific rules, and in this case, it is not possible for two O positive parents to have a child with blood type A positive.
Yes. The geneotype for both parents must be AO+- for the child to be OO--
There are no limitations on compatibility of parents based on blood type. Two O positive parents may have a child without any special concerns.
No. O is recessive. The parents would have to have A and B phenotypes in order for their child to have AB- blood.
most probably not.
No, two O positive parents cannot have an AB positive baby. Inheritance of blood type follows specific patterns, and a child cannot have a blood type that is not possible based on the parents' blood types.
No, two parents with O type blood cannot have a child with B type blood. This is because O is recessive - meaning in order to have type O blood, you need to have two O alleles. Therefore if both parents have O blood, all their children have to have O type blood. In order to have a child with B type blood, at least one parent needs to have B or AB type blood - in order to donate the B allele to the child.
