blood group "A" or "O".
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
if both parents have positive o blood their child must have positive o blood
yes it is possoble, each child is different and the parents blood type determains the child's. but both children will have a positive no matter what because both parents have positive.
No. Generally when both parents are Type O+ they produce Type O+ or O- children. See also: http://www.bloodbook.com/inherited.html
No - if both parents have blood type O, then the only possibility for their children is also blood type O. If they are both heterozygous for Rh (+/-) then they could have either + or - children. If either of them are homozygous (Rh+Rh+) then all the children will be +.
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
No. If both parents are Rh negative, they are homozygous recessive for the Rh factor and can only pass on recessive alleles to their children, and a positive Rh factor is a dominant trait.
yes
probably because the child usually has the same blood type as the mother due to it being in her body.
No. If both parents have type O blood then they will only be able to have children with type O blood.
