Can a type O child have a father with type A blood and how?

Answer 1

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

Since there are 4 different maternal blood types and 4 different paternal blood types possible, there are 16 different combinations to consider when predicting the blood type of children.

Answer 2

As O is recessive, to display O bloodtype (phenotype) must mean the child has a genotype of OO. It therefore received an O allele from each parent. If the father has type A blood (phenotype), his genotype must be AO (remember he must have given an O to his kid, so he must have an O).
The mother can really be anything with an O: AO (blood type A), BO (not just a smell, blood type B) or OO (blood type O).
The only thing the mother cannot be is blood type AB.

Answer 3

yes. the blood group is genetically propagated in a multiple allelic type of inheritence. there are three different kinds of alleles for the blood group. one Ia,Ib and Io. Ia and Ib are codominant whereas the Io allele is recessive i.e. it can be expressed only if present in the homozygous state. so if the father is a heterozygous of the genotype IaIo and the mother is either of the blood group O(50% chances), or a heterozugous for A or B as in the fathers case there is a (1 in 16)chance that the child will have a blood group O. it is an autosomally transmitted character.

Answer 4

check the website listed below .

A type O child can have a father with type A,B or O depending on the mothers blood type.

Blood type can not prove paternity. It may exclude a man because the blood types are incompatible.

Answer 5

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

B from the father Child~~B

Answer 6

Yes they can. Blood type is determined by a pair of alleles therefore if he is AO and the mother has at least one O gene then the child may inherit O from both and end up with blood type O.

Answer 7

Yes, it is possible. Type O is a homozygous recessive condition. So the only way it could happen is if your genotype is OO. If you had one parent(the father) and his genotype was AO his phenotype (or what his blood type would be) would be A because it is dominant to O. If the mother had either AO or OO then you would have kids that could have blood type O, but that's the only way. I can't do the punnett square to show what the results would be

Answer 8

absolutely yes...
basically from my study..
but both of their parents must be heterozygous (whether A heterozygous or B heterozygous)
as we know,
type blood A could have genotype of AA (homozygous dominant) or AO (heterozygous)

for example: mating of heterozygous of A


Let’s we cross heterozygous of A blood type (both parents)


Parents AO x AO


Gametes A O A O



BY USING PUNNET’S SQUARE, WE CAN DETERMINE THE PROBABILITY OF THE OFFSPRING (PROGENY).SPECIFICALLY, HAVING TYPE O CHILD


gametes A O
A AA AO
O AO OO

AS A RESULT,ONLY ¼ OF CHILD WILL HAVE O BLOOD TYPE DUE TO IT'S RECESSIVE TRAIT

good luck
