Yes, this is true.
100% of all children will have a negative blood type.
It is not possible for two parents with blood type O negative to have a child with blood type AB. In the ABO blood group system, type O is recessive and AB is a combination of A and B, making it impossible for two parents with type O blood to produce a child with type AB blood.
If both parents are O negative, their child will also be O negative. This is because O negative is a recessive blood type that requires both parents to contribute an O negative allele for the child to have O negative blood type.
No.
No, parents with B negative and AB positive blood types cannot have a child with O negative blood type. The O blood type is inherited from both parents who must pass on the O allele to the child. Since neither parent in this case carries the O allele, they cannot have a child with O negative blood type.
Yes, two parents with negative blood factors (e.g. O-) can have a child with a negative blood factor (e.g. O-). Blood type inheritance follows specific patterns, so it is possible for two negative blood factor parents to pass on the negative factor to their child.
It is not possible for two parents with blood type O negative to have a child with blood type AB. In the ABO blood group system, type O is recessive and AB is a combination of A and B, making it impossible for two parents with type O blood to produce a child with type AB blood.
yes they can
If a child does not have the same blood type as either the father or the mother there is nothing to worry about. It is fairly common for a child to have a blood type that combines the blood types of the parents, such as an AB negative child whose parents had A negative and B negative blood.
Yes, O negative
If both parents are O negative, their child will also be O negative. This is because O negative is a recessive blood type that requires both parents to contribute an O negative allele for the child to have O negative blood type.
If both parents have Type B blood the only blood type the child can have is either B or O not looking at whether one of the parents is negative or not.
most probably not.
No.
No, parents with B negative and AB positive blood types cannot have a child with O negative blood type. The O blood type is inherited from both parents who must pass on the O allele to the child. Since neither parent in this case carries the O allele, they cannot have a child with O negative blood type.
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
Yes
Only if he's adopted. Parents with a + blood type can have children with a - blood type, but parents with an O bloodtypes can only have O type children together.
