Introduction. A cleft is a gap or split in the upper lip, the roof of the mouth (palate), or sometimes both. It occurs when separate areas of the face do not join together properly when a baby is developing during pregnancy.
What this means is that now the appearance of a feature like a cleft chin is dependent on two genes, the modifier gene and the cleft gene itself. If both copies of the modifier gene lead to no cleft chin, then the cleft chin gene won't matter -- it will be silenced.
