A punnett square:
The parents: Cc and cc
Ends up with progeny (offspring) with genotypes:
Cc - cleft chin (heterozygous dominant)
Cc - cleft chin
cc - "normal"
cc - "normal" (homozygous recessive)
(1:1 ratio affected: unaffected)

punnet squares are all you need set it up as Cc on top and cc on the left side do the lattice a cc is recessive and a CC or Cc is dominant

Do a punnett square.
Mom: Cc
Dad: cc (or vice-versa, it's the same)
MOM: C c
DAD
c Cc cc
c cc cc
