Question

The offspring of a cross between a plant with purple flowers are 23 plants with purple flowers and 26 plants with white flowers. What are the genotypes of the parent plants?

Answer 1

Assuming purple is dominant, the genotypes of the parents must be Pp and pp, such that half the progeny have the dominant allele (P_) and half have the recessive phenotype (pp) 25% possibility of white-flowered plant life and 75% possibility of pink ones
