|
|
Type A is dominant over blood type B
|
|
|
Baby Phil has blood type A and the parents must have a different blood type
|
|
|
Both parents had blood type A; neither could have given Baby Phil the B allele
|
Detailed explanation-1: -In incomplete dominance, the heterozygote has a phenotype intermediate between that of homozygous-dominant and homozygous-recessive individuals. Normal vision is dictated by the autosomal dominant genes. It is possible for a baby to have type O blood if neither parent is type O.
Detailed explanation-2: -If both the parents are AB then their genotypes will be IA/IB and this combination cannot give rise to O blood group.
Detailed explanation-3: -. (AB blood group). So, the possible IB blood groups of children born in this case are A, B, and AB blood groups. .
Detailed explanation-4: -Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.
