What would be a child's blood type if the mother is a plus and the father is o plus?
Since the mother has an "O" blood type (which is recessive), she can only pass down "O" blood type alleles. This means both children must have at least one "O" allele (whether they express it depends on the allele they inherit from their father). Since the mother is RH positive, she has to have at least one positive allele. It is possible she carries a recessive RH negative allele. (An allele makes up half of your genes: one from dad, one from mom.)
This being said, we can now determine what alleles the children got from the mother and, by process of elimination, what was inherited by the father. The O negative child would have two O alleles, which means the parents must each have had an O allele. The negative allele again is recessive, so for the child to express this, he/she must have gotten a negative allele from both parents. This confirms that the mother has a recessive negative allele, although her blood type is O positive.
Now the B positive child gives us more limitations on what the father could be. The mother would have passed down an O allele to this second child, meaning that the B allele must have come from the father. The positive allele could have come from either the father or the mother (since the mother has a positive and negative allele), so it is undetermined what RH alleles the father completely has.
Since the father must have an O allele to pass down to the first child, a negative allele to pass down to the first child, and a B allele to pass down to the second child, it leaves us with only two possibilities of the father's blood-type:
B positive or B negative.
Hopefully this helps, but do remember that blood type is not completely a reliable way to eliminate a father. Any mutations in the child's genes may have caused him to express an allele that was not from the father, thus a paternity test would still be needed to know for sure. But from what we learn in High School Biology, "B+" and "B-" would be the correct answers in this case and probably follow 90% of the time (I am estimating here.)
What else can I help you with?
If a mother has O negative blood and her child has A positive blood what type of blood should the father have?
The blood would be A+, the child's is always pretty much what the Father's is.
Can a mother with blood group O and gather blood group AB produce O blood group child?
Yes, it is possible for a mother with blood group O and a father with blood group AB to have a child with blood group O. This would occur if the child inherited the O allele from the mother and the O allele from the father.
Can b positive child have an a negative father?
Yes, it is possible for a child to have a different blood type than their father. A child inherits one blood type allele from each parent, so if the child receives a B allele from their mother and an A allele from their father, they can have blood type B.
What would be the blood type of the child if the mother is B plus and the father is A plus?
ab+ a+ b+
If the father is o positive and mother is o positive what would the child's blood group be?
O positive
What is a childs first connection to the world?
A child's first connection would be their parents (mother and father). Their next connection would be their siblings (brothers or sisters) if any.
If a father is a plus blood type what type would his children have?
Blood type is a combination of the mother's and the father's genes.
If a mother has type A blood and her baby has type B blood what blood type would the father have?
The father could be AB or B.
What would the Blood type of a child be if mother was A plus and father was A?
A+
Two siblings are O- born first and then A . The father was O What blood type must the mother be?
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
If a mother has O negative blood and her child has A positive blood what type of blood should the father have?
The blood would be A+, the child's is always pretty much what the Father's is.
What is the baby if Father is a mother is b?
The Baby Would Be Type A Blood
Why might a person have curly hair or straight?
usualy if a childs mother or father has curly hair they to would probaby have curly hair to because it is a genetic thing
If the father has b positive blood and the mother has o positive blood what would the child's blood type be?
o blood
If the father has b positive blood and the mother has a positive blood what type would the child be?
Probably AB+ blood.
What blood type is the father if the mother is AB and the baby is AB?
The father would be either AB or AA.
Can a mother with B- blood type and a father with O plus blood type have a baby with B plus blood type?
Yes, it is possible. The geneotype of the mother would be either BB or BO and for the father would be OO. If you cross the father's geneotype and either of the mother's then at least two of the four outcomes will be for B blood type. As for the - and +, positive is dominant over negative. The father could be + - or + + and the mother would be - -. Either combination would result in at least two positives. Therefore, it is possible for the mother to be B-, the father to be O+ and the baby to be B+. I added the link to the website where I got my info from. I want to know if an rh b neg blood type mother and an O positive father can have an A positive baby?
