Answer 1

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.

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."
