This occurs in dihybrid crosses
There is a 9/16 chance of the offspring have all dominant traits
A 3/16 chance of the offsprings traits being dom/rec or rec/dom
A 1/16 chance of the traits being all recessive.

For example if Tall is dominant to short and Red is dominant to green
9/16ths of the offspring will be Tall and Red
3/16ths will be either Tall and green OR short and Red
1/16ths chance the offspring will be short and green
