Question

1. A Mendelian experiment consisted of breeding tall pea plants bearing violet flow
with short pea plants bearing white flowers. The progeny all bore violet flow
but almost half of them were short. This suggests that the genetic make-up of
tall parent can be depicted as
(a) TTWW
(b) TTww
le) TWW
(d) TWw
plz explain​

Answer 1

We know that tallness is a dominant allele ( TT ) and violet flower colour ( WW ) is also a dominant allele.

So,

TTWW is the correct answer.

Answer 2

Answer: a) TTWW

Explanation: This is because:

Violet is a dominant character and white is a recessive character so when we cross voilet with white the colour violet appears in the flower.

Whereas the height of a short plant is a recessive therefore during the second cross most of the plants were hybrid tall along with dwarf plants

That is In the ratio : 3:1

Sorry for my mistake I didn't check the answer after writing it but explanation is OK. Hopes it help
