Subsequently, one may also ask, can a father and daughter have a healthy baby?
The children are healthy, but like their mother and father, they have a genetic defect that they can pass on to their children. A child with the combination a-a has inherited a genetic defect from both parents, meaning this child will get the disease. The child can be born with the disease or develop it later in life.
Beside above, what would happen if a brother and sister have a baby? The risk for passing down a genetic disease is much higher for siblings than first cousins. To be more specific, two siblings who have kids together have a higher chance of passing on a recessive disease to their kids. But usually they only cause the disease if both copies of a gene don't work.
Just so, what does a baby inherit from the father?
Among the physical traits inherited from father, teeth structure is hereditary. There is a gene which determines the gap which comes between teeth. If the father has a gap tooth, it is very likely the baby will have as well.
Can I have a baby and not tell the father?
Nope. You have no legal obligation to let him know. "It's a woman's right to choose whether she proceeds with the pregnancy or not, and there is nothing to compel her to tell the guy she was with," Jenny says.
