You are studying inheritance patterns in toads.
You have two populations of toads that are true breeding for two genes.
There is a gene that controls skin texture (some toads have bumpy skin and others have smooth skin). Another gene controls skin lubrication (some toads are slimy while others are dry). Both genes have only these two variations.
Toads in population A have bumpy, slimy skin.
Toads in population B have smooth, dry skin.
Both populations of toads are true breeding, therefore
