The offspring of a cross between a plant with purple flowers and a plant with white flowers are 23 plansts wit

h purple flowers and 26 flowers with white flowers. What are the genotypes of the parent plants? use the letter P for purple plants and p for white
Say
FlowersBirthday FlowersSympathy Flowerswith a question like this you're usually given which trait is dominant and which is recessive.. and its hard to tell with the offspring in a roughly 1:1 ratio.





BUT 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).computer
