Answer:
75% is the probability of purple-flowered offspring if a cross between one plant is heterozygous for purple flowers and the other has white flowers.
Step-by-step explanation:
Purple flower is a dominant trait and a white flower is said t be recessive trait.Let us assume P is dominant trait and p is a recessive trait. So, each plant will produce gametes of two types P and p.
By Punnet Square method, it has been observed that 75% plant will have only one dominant trait and thus it will bear purple flowers."
