What gene is responsible for cleft chin?
AncestryDNA tests one genetic marker, rs11684042, which is found on chromosome 2. It’s involved in cleft chins, but it is by no means the whole story. Lots of other parts of your DNA, as well as environmental factors, play a role in whether or not you will have a cleft chin too.
Is cleft chin a male trait?
Having one parent pass down this genetic mutation gives you a 50% chance of developing a cleft chin. Men and women have an equal chance of passing down the trait. Sons and daughters are equally likely to develop this. If both parents pass down the genetic mutation, your chances of developing the trait increase.
What percentage of cleft chin child will the parents probably have?
a 50% chance
Since the father has a smooth chin—therefore homozygous for the recessive allele (bb)—we can expect the offspring to have a 50% chance of having a cleft chin and a 50% chance of having a smooth chin (Figure 4).
