Question
1. Two F₁ parents are crossed:
F₂ generation
Rr x Rr
2. Make a Punnett Square using those F₁ parents and determine the possible
types of offspring (F₂ generation).
3. Based on your Punnett Square, complete the sentences below:
a. The F₂ phenotypic ratio should be
Purple:
b. The F₂ genotypic ratio should be_
4. Based on your predictions in the Punnett Square, the ratio of F₂ phenotypes should have
been 3 Purple: 1 yellow.
a. What ratio did we actually get when we counted F₂ kernels?
RR:
yellow
Rr:
b. If we had counted 5 times as many corn kernels, would we have been closer to
_Why?
the predicted ratio?_
