Is it true that children's blood group is more similar 2 their mother's blood group?

Answer 1

well...i'd say yes...i am blood type o positive and all 3 of my kids are o positive....

Answer 2

No. Blood group and type is determined by both the mother and father. Here is a simplified explanation of how it works. There are 4 blood groups: A, B, AB and O. The types are either either Rh+ or Rh- , with Rh+ being dominant. The genotypes of the groups show as the following:
A can be AA, AO
B can be BB, BO
AB can be AB
O can be OO
Out of the blood types O is recessive, so in order for the child to be O both parents have to be carriers of the gene. For example if one father is AB, then the child cannot be O even if the mother is. With that example the child could only be either A or B blood type.
I hope this didn't confuse the issue more for you... genetics can get quite confusing until you understand it. Feel free to contact me if you want further explanation.

Answer 3

Not necessarily. It is inherited like all other genetic traits with one component from each parent. There isn't any predominance towards either parent per se. It may happen that a child can have the same blood type as their mother (ie, my father is b neg, my mother is o neg, I'm o neg. However, I could have just as easily been b neg as well).

Answer 4

It is going to be a random combination between the father's genotype and the mother's genotype. O is recessive, A and B are co-dominant.

Answer 5

not true.
I heard a case:
father is A
and mother is AB

the offspring is O.

It is possible with a factor: Bombay phenotype

Answer 6

should be either mother or father or combined

Answer 7

either or combined
