Well first you should radio all others on scene and explain what you saw and where you saw it.

So first off homozygous means that both alleles are the same
If coiling to the right is dominant and to the left is recessive let capital c (C) represent right coiling and let lower case c (c) represent left coiling.
The female who is homozygous recessive must have both recessive alleles
The male who is homozygous must have two dominant alleles
So the cross will be between a CC and a cc
So we set up a Punnett square
We take a look at all the combinations and arrange them
So we find that there is a 25% chance of the offspring having left coiling
Each chromosome contains one molecule.
