If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered
plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first
generation of offspring should have

All purple flowers

Explanation: Set up a Punnett square with P for the dominant gene and p for the recessive. The purple-flowered plant would be PP and the white- flowered plant would be pp. All of the offspring would have the genotype Pp. Since purple (P) is dominant, all of them would be purple.

answer; /// i believe that the correct answer is; ///a combination of the birth and death

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
