Goryan [66]

Answer:

9:3:3:1

Explanation:

This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).

According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:

TtPp - TP, Tp, tP, tp

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

T_P_ (tall, purple) = 9

T_pp (tall, white) = 3

ttP_ (short, purple) = 3

ttpp (short, white) = 1

Hence, the ratio of this cross is 9:3:3:1
