Can two people without a clef chin have a child with a clef chin?

Question:

Can two people without a clef chin have a child with a clef chin?

My friend has a child who looks NOTHING like him. The child also has a clef chin and neither my friend nor the childs mother has one. Im not sure but I thought that in order for a child to have this trait one of the parents had to have it.

Best Answer - Chosen by Asker: My daughter has a little clef chin and neither my husband nor I do (and yes, he is her father, and yes, I'm sure!). My guess would be that it is recessive and both parents could have the trait without expression, but I don't know that. I just know I have a child with a clef chin and 2 parents without. Google might turn something up. My daughter looked little like her dad until she turned about 6 or 7, now she looks a little more like him than me. Kids look like all combinations of their parents, and more like them as they get older.

OK, I was curious. I found a site that worked out the punnett square: there is a 3:16 chance that parents without expressed cleft chins will have a child with one!
