Generally speaking a Type A mom who is genetically AA cannot have a Type O baby (genetically OO) because she would not have the necessary O gene to offer the baby.
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
If the baby's inhibitory gene has been turned "on", then no matter what ABO genes he receives from his parents, he will test out as a Type O.
What else can I help you with?
If the mom is o and the dad is a what blood type will be their baby?
The baby will either be blood type O or Type A
Mom's blood type is O- Dad's blood type is O plus Can Baby's blood type be A plus?
No, because O is recessive. So, the mom and dad both have OO alleles for blood types. Due to that, they each have to give the baby an O allele, so the baby will be OO.
Can a mom with blood type o positive and a father with blood type b positive have an a negative child?
sadly, no. no matter what you do, a blood type B and blood type O couple cannot have a blood type A (+ or -) baby
How does a baby have o blood type and mom has ab and dad has b?
A baby with O blood type can be born to a mother with AB blood type and a father with B blood type if the mother is a carrier of the O blood type allele from a parent and passes it on to the baby. The baby inherits one O allele from the mother and one B allele from the father, resulting in O blood type.
If dad has blood type A and mom has blood type B can they have a child with blood type O?
Yes. Type O blood requires that you have two recessive genes, one from each parent. Each of your parents can carry one of these and have a different type of blood. In this case, there is a one in four chances of the child having type O blood.
Can a woman with type a rhnegative blood have a healthy baby with type b rh positive blood?
We are looking for the possible blood types of the FATHER.Available information:Mother type B -- can be BB or BO = contributes B or O geneBaby type A -- can be AA or AO = must recieve O from mom & A from dadBaby receives one gene from each parent: Mom is BO and Dad is AA = baby AO or ABMom is BO and Dad is AO = baby AO, AB or OOMom is BO and DAd is AB = baby AO, AB, BBIf the mom is heterozygous Type B, and the dad is Type A or AB, then they could have a baby who is Type A.
Who determines the blood of a baby comes from de mom or pa?
Blood type is not a sex-linked trait. Both parents contribute equally to determine a child's blood type.
Can a baby born with type AB blood belong to a dad that has type A blood and mom has type O?
No...from what I have learned in biology, the way blood types are gotten are from the parents, and blood type A is I^aI^a or I^a^i , while blood type o is ii...the possible blood types that can come from it is type a and type o...there cannot be b or an because there is no b gene in it anywhere.
Can a mom a blood type and a dad with b blood type have a child with o blood type?
yes
What will baby's blood type be if mom's is AB and dad is o?
Could be anything, we get our blood group from either parents or grandparents.
Is it possible to have a child with blood type O if the mom has blood type A and the dad has blood type B?
yes
Why check baby's blood type when mom is O positive?
Checking the baby's blood type is important when the mom is O positive because there is a risk of hemolytic disease of the newborn if the baby is Rh positive. This occurs when the mother's immune system attacks the baby's red blood cells if they are Rh positive. Identifying the baby's blood type helps in managing any potential complications.
