Question

A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers The progeny all bore violet flowers, but almost half of them were short This suggests that the genetic makeup of the tall parents can be depicted as [NCERT]
(a) TTWW
(b) TTww
(c) TtWW
(d) TtWw

Answer 1

Answer:

The genetic makeup is TtWW

Explanation:

If we consider tall trait as ‘T’ and short as ‘t’. For the violet we can use ‘W’ and for white we are going to use ‘w’. After the breeding progeny obtained was all violet flowers with half tall and half short result. We can depict that the genetic makeup of tall parent is TtWW.

This is because after the dihybid cross dominant trait was violet flowers with the dominant tall parent but a recessive short. It cannot be TTWW because in this case the ratio will be 9:3:1:1.

Answer 2

Answer:

TtWW is your answer bro
