A baby is born with a genetic disorder that did not affect either of the parents

4 -- A child born with a recessive condition has inherited one altered gene from the mother and one from the father. In most cases, neither of the parents is affected and therefore, each of the parents must have a single gene alteration on one chromosome of a pair and the normal, wild-type, or unaltered, form of the gene on the other chromosome. These parents would be known as carriers of the condition and they do not usually exhibit any signs and symptoms of the condition. If only one parent was affected, the child would not be born with the disorder but simply be a carrier as well. There is no evidence to support the fact the father is not the biological father.
