The Punnett square above shows a cross between two sweet pea plants in Mendel's greenhouse. Both parents have purple flowers (Pp). Which statement describes the offspring expected from this cross?
A) 50% white-flowered and 50% purple-flowered
B) 75% white-flowered and 25% purple-flowered
C) 75% purple-flowered and 25% white-flowered
D) 100% purple-flowered and 0% white-flowered

Answers

Answer: The correct answer is-

C) 75% purple-flowered and 25% white-flowered.

As per the information given in the question, genotypes of parent plants are-

Pp and Pp that is heterozygous dominant, which exhibit purple flowers.

This indicates that purple flower is a dominant trait that masks the expression of recessive trait.

A dominant trait ( depicted by capital letter allele) always masks the expression of recessive trait ( depicted by small letter allele).

When parent plants with heterozygous dominant ( having two different alleles that is dominant and recessive allele) genotype are crossed, they will produce 75% purple-flowered and 25% white-flowered plants.

Refer punnet square.

c is definitely the correct answer
