Can a child have a different genotype from the parents?

Can a child’s genotype be different from the parents?

The pattern of genes we have is called genotype and the form in which it is expressed is called phenotype. It is the genotype (genetic make-up) which decides what the blood group (phenotype) will be.

Can a child have a blood group different from his/her parents?

Blood group of parents Blood group of child
B and AB A, B, AB
B and O B, O
AB and AB A, B, AB
AB and O A, B

Can a child have type O blood if parents have A and B?

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).

Can two O positive parents make an O negative child?

A. Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children. In fact, according to the experts, most children who are O-negative have parents who are O-positive.

Why is my blood type different from my parents?

Blood Inheritance

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

How can baby have different blood type than parents?

What causes blood type incompatibility? Blood type and factors are determined by genetics. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. The Rh positive gene is dominant (stronger) and even when paired with an Rh negative gene, the positive gene takes over.

Can two O+ parents have an A+ baby?

It is not possible for two parents of the genotype described in the question to have a type A+ offspring.

Can Type A and B make O?

Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types.

How does a child get O blood?

If one parent contributes and A gene and the other contributes an O gene, the child will have A blood type, but, like his parents, he’ll also have both A and O genes that he may pass along to his children. However, in 1 out of 4 instances, both parents will contribute their recessive O gene to their child.
