Yes if the A and B spouses were heterogenous, they could produce a child with type O blood.

Can an a positive father and an b negative mother have an ab negative child?
yes it dependsupon the genotype and phenotype
What phenotype is produced by AA genotype?
If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.
If mother blood is b negative and father blood is ab positive what is child's possible blood group?
If the mother's genotype is BB, the child can be type B or AB (50/50 chance). The child cannot be type A or O. If the mother's genotype is BO, the child can be any type, tho B or AB is more likely. The Rh factor is likely positive but can be negative. So, without knowing the mother's genotype, and the father's specific Rh factor (++ or +-), we cannot be sure.
What genotype is produced by the phenotype B?
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
Can a a positive mother and a o negative father produce a o positive daughter?
It depends on the mothers genotype for the ABO system. Genotype is what happens at the gene level as her phenotype (what she expresses as a result of her genotype as a whole) is A.Each parent donates one half of the child's genotype.In the ABO system, A and B are co-dominant over O (O stands for Lack of Antigen).Meaning if you have a genotype of A/O you will be A.Below is a list of possible genotypes and their phenotypes (what the person's blood type will be)Genotype Phenotype (Blood Type)A/A AA/B ABA/O AB/B BB/O BO/O OThe mother either has a genotype of A/O or A/A (one from each of her parents) if she has an A bloodtype.Providing the father is definitely O,If she is A/A, all of her children will be A (child's genotype is A/O)If she is A/O, there is a 50% chance of her children being O (child's genotype - O/O) and 50% A (Genotype A/O)The child be will be rhesus positive as their is only one locus for the gene and it is dominant.(You can only become rhesus negative if both parents are Rhesus Negative.Genotype Phenotype (Rhesus)Pos/Pos PosPos/Neg PosNeg/Neg Neg
A woman is homozygous for A-negative blood type. A man has AB-negative blood type. What is the probability that the couples child will be type B-negative?
The genotype of the man is A negative/O negative inheriting the A neg from his mother and O negative from his father. [Father's genotype is B positive/O negative. Mother's genotype is B positive/A negative.]
Can a O positive and B negative produce baby A negative?
Yes. The long answer is to distinguish phenotype (the blood type A, B, AB, O) from genotype (what pair of alleles compose your genes (AA, AO, BB, BO, AB, OO). The same goes for Rh factor (positive or negative), although the theory is more complex. The Rh + is usually taken to mean positive for the D antigen. So parents having O (must be OA genotype) and B (must be BO genotype) blood can have a child with A ( will be AO genotype).
Can an a positive father and an b negative mother have an ab negative child?
yes it dependsupon the genotype and phenotype
What phenotype is produced by AA genotype?
If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.
Your blood is b positive and your girl frend is b negative can you marry her?
I can assure you, you guys can marry, no problem.
Is the b negative and b plus genotype of a baby exist altogether?
yes beacuase justin beiber has AB blood
Does A negative can marry B positive?
A person with A- can marry a person with B+. There are no limitations on marriages based on blodo type.
Will a mother's blood produce antibodies if the mother is B positive and the baby is B negative?
The mother will be given Rhogam injection within 72 hours to prevent formation of antibodies to protect the 2nd baby that he will be conceiving.
Can an A1 negative blood group girl marry a B negative blood group boy?
no
Can B negative girl marry a O positive boy?
yes
Can a o positive boy marry b negative girl?
yes
Can a b positive boy marry o negative girl?
yes
