I dont think that if the mother is happy, then the child is. Children who look to there parents don't have to tread in their foot steps. Or the other way round, if the mother is moody doesnt mean that the child is.
Yes, they can.
rarely can be
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
Yes, with a percentage reaches only to 25%.
Yes. Both parents have an A allele and a B allele. Each parent can only pass on one of his/her two alleles. If each parent passes an A allele to the child, then the child will have group A blood. If at least one parent passes on an Rh positive allele to the child, then the child would also be type Rh positive. So these two parents could have an A positive child.
Yes, it is possible for a child to have O positive blood type if one parent is O positive and the other parent is A positive. The child could inherit the O allele from the O positive parent and the A allele from the A positive parent.
yes
no
A child with blood group AB positive cannot be a biological child of a parent with blood group B positive, as the ABO blood group system does not allow for this combination. The possible blood groups of a child from a B positive parent could be B or O. Therefore, the child is not a match in terms of biological parentage.
No. If both parents are Rh+, they can only pass on Rh+.
No, an O-group parent cannot have an AB-group child at all.
Yes.
