Group of answer choices

True

False

Answer 1

Answer:

False

Explanation

Let's call the orange flower, Rr, and the red flower, RR. By using a Punnett square you create a square with four boxes inside the square. On top of two boxes, you write Rr. To the left of two boxes, you write RR. In the first box you take the R from the orange flower and R from the red flower making it RR, thus it's red. The same is done for the box underneath it. The other two boxes get an R from the red flower and an r from the orange flower, making it Rr or orange. So 2 out of 4 of the boxes have the orange flower. 2 out of 4 is 50%
