Gene transmission to new generations is a crap shoot.. It's like throwing up the dice from two places and seeing what lands on the felt. If the baby looks mostly like one parent, that is probably gonna stay that way. However, there are a lot of characteristics that are not as visible. Intelligence, teeth, hair color, math abilities, etc. are all kinds of characteristics that might apply. There are dominant genes and regressive genes. The result is that both sides must deliver the regressive gene for it to be expressed.
It is possible with dominate and resistive genes. If mom passed down a dominate gene and dad is resistive then the child will more than likely look like the mother. Useing a Punnett square will help you with this question.
