Genetic Diagrams

If one single gene showed how muscular a mouse was.

And that dominant allele would code for a normal mouse, and the recessive allele for a muscular mouse. The typical question for this topic can be draw a genetic diagram for the cross between a homozygous normal mouse and a homozygous muscular mouse.

Although a single gene normally doesn’t determine a single trait, but it is true that genes interact.
