yes, i study DNA, and it is possible for a child to have different blood group to a father, if you want to chaeck they do it free at the doctors
A or AB
If a mother has blood group 0 positive and the father is also 0 positive can they give birth to a child with blood group 0 negative?
The mother and father both have heterozygous alleles for the blood group A. The blood group A can have the alleles AA or AO, when both parents are AO, there is a one in four chance that the child will have blood group O as this blood group is recessive.
o
The mother would have to be type A. Father has genotype (0,0) Mother would need to have genotype (A,0) - fenotype (blood group) = A
The blood group that is most common is 0+. It is a universal blood type.
Then the father of the child is someone else with B Negative blood group.
No. The child will be either group A or group B, but not group O. This is because the father can donate only a group A gene or a group B gene, so since group A and group B are dominant over group O, the child could not have group O blood.
yes
yes
I was told that a mother that is a+ and child is 0+ that it OK for the father to be 0-
According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). Blood group A If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. Blood group B If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Blood group AB If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. Blood group 0 If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.
