Question

A plant can produce either purple flowers or white flowers. What is the probability of purple-flowered offspring if a cross between one plant is heterozygous for purple flowers and the other has white flowers?

0%
25%
50%
75%

Answer 1

The answer is 50%!

Step-by-step explanation:

The genotypes will be Pp and pp which will mean that the offspring will be Pp, Pp, pp, pp; which means that there will be 2 purple and 2 white flowers (purple is dominant while white is recessive).

2 : 4 = 50%

Answer 2

The answer is 0% because if you do a Punnett square there are all dominant White traits.
