Heather was breeding flowers and claimed from her experimental results that when you cross a red flower (dominant, R) with a white flower (recessive, r), you will always get red offspring. She made the following model to illustrate her claim.

Question

Heather was breeding flowers and claimed from her experimental results that when you cross a red flower (dominant, R) with a white flower (recessive, r), you will always get red offspring. She made the following model to illustrate her claim.

RR x rr -red

Her friend, Jamel, performed a similar experiment, and claimed that you can cross the red and white flowers and get both red and white offspring.

Which model supports Jamel’s claim?
A RR x rr - red or white

B Rr x Rr - red or white

C Rr x rr - red or white

D rr x rr red or white

Answer 1

Heather was breeding flowers and claimed from her experimental results that when you cross a red flower (dominant, R) with a white flower (recessive, r), you will always get red offspring. She made the following model to illustrate her claim.

The model that supports Jamel’s claim is B - Rr x Rr - red or white.
