No, it's not possible. Someone with type A blood has the genotype AA or AO, so if both parents are type A their children could only be type A or type O.
eg if the mother was genotype AA and father also AA, their children could only be AA (i.e. homozygous for blood type A), but if the mother were AO and the father AO (i.e. heterozygous), then their children could be AA, AO, or OO (i.e. blood type O). If the mother was AO but the father AA, then their children could be AO or AA but not OO. This is due to the way genetic information is passed from parent to child; male gametes (sperm) contain 23 paternal chromosomes and female gametes (egg) contain 23 maternal chromosomes, so when they fuse at conception to form the foetus (46 chromosomes as everyone has, except those with certain genetic disorders), it has 50% genetic information from the father, and 50% from the mother.
What else can I help you with?
If both parents have A blood type can they have a child with o blood type?
Yes. Both parents could be heterozygous, that is AO, and pass on the O to their child.
Could a child with type B blood have parents that are both type A blood?
Only if it was adopted...the only options for that child's blood type would be A or O if the biological parents are both Type A.
If both parents have 0 positive blood types could child have type A?
No.
If both parents are A positive can a child have negative blood?
Yes. If both parents have the recessive gene for Rh negative, a child of theirs could have Rh negative blood. I have two daughters who are Aneg, and both of us are A+.
How could a child have A blood type when parents are both o plus?
It's not possible for two O+ parents to have a child with A blood type. A child's blood type is determined by the combination of genes inherited from the parents, and in this case, the genetic combination would result in the child also having O+ blood type. A possible explanation could be an error in blood typing or paternity.
Blood group can two A people have a child who is O?
Yes this could happen if the geno-type of both parents is heterozygous, what i mean by that is to have this symbol for both parents : IAi X IAi so to have a child with type O, the possibility for that is 25%
If both parents have o positive blood how can the child have o positive L blood?
if both parents have positive o blood their child must have positive o blood
What could be the reason why a child is born with A blood types and both parents are O plus could the parents parent be a carrier of A blood type?
Parents should re-test their blood types to check if there was any error in their past result. there is no way to have A blood type baby if both were O
What will the baby have if the parents' blood types are O plus?
If both parents have blood type O, the child will also have blood type O. This is because O is recessive (meaning a person can only have O type blood if they have two O alleles).Rh positive is dominant, so that means that the parents could have the alleles +- or ++.If both parents are +-, it means their child could be either Rh positive or negative.If either parent is homozygous (both allleles are positive), then the child will also be Rh positive.
Can a mother with a plus blood and a father with b plus blood make a baby with o plus blood?
It could be possible, but only if both the parents are heterozygous.If the mother is AO and the father is BO - there is a 25% chance the child will be OO (O blood group).However, if either or both of the parents are homozygous (AA or BB) - then they cannot have an O child.
Is it safe to have a child if both parents are 0 negative?
Can parents with both negative blood have a child and how much of a chance for that child having a dissabillity
Is it true that the blood of a child comes from the sperm from the father and not the mother?
No. The child is a unique mix of both of its parents.
