Grain color is one trait. Grain texture is a second trait. For each, what do you notice about the
phenotypic ratios?
P = Purple; p = Yellow; S = Smooth; s = Wrinkled
A genetic cross involving heterozygotes with only one trait is a monohybrid cross.
A genetic cross involving heterozygotes with two traits is called a dihybrid cross.
Consider the cross PPSS x ppss (Parental Generation). The F1 generation is the result of the cross.
Gametes: PS for one parent (e.g. the egg) and ps for another parent (e.g. the sperm).
