Question

Purple flower color (P) is dominant over white flower color (p) in pea plants. A heterozygous pea plant with purple flowers is crossed with another heterozygous pea plant with purple flowers.

What will be the phenotypes, and probabilities of their offspring?

Question 11 options:

75% purple and 25% white
100% purple
100% white
50% purple and 50% white

Answer 1

75% purple and 25% white

Step-by-step explanation:

When a punnett square is drawn to predict the phenotypes of the pea plants offspring:

- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)

- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)
