Question

A pink-flowered Mirabilis plant (RW) is crossed with a white-flowered Mirabilis (WW). What is the chance that a seed from this cross will produce a white-flowered plant?


A. 1

B. 1/2

Answer 1

The picture I attached is a punnett square that show the cross between the two flowers and the possible combination of offspring from such a cross.  The answer would be B

Answer 2

Answer:

B. 1/2

Explanation:

To know what happens with the offspring, you need to know about the parents.

You know the pink flower is RW this says that both alleles are dominantly white, and red together they do pink.

So, if you to the Punnett square you will find that 50% of the offspring are WW and 50% of the offspring are RW
