Science
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 make-up of the tall parent can be depicted as
- TTWW
- TTww
- TtWW
- TtWw

Answer
TtWW
Reason — Possibility of genotype for parent plants:
- Tall pea plants bearing violet flowers — TTWw or TtWw or TTWW or TtWW
- Short pea plants bearing white flowers — ttww or ttWw
Since, the progeny all bore violet flowers, the tall parent must be homozygous for violet flower colour i.e. WW. Also, almost half of the progeny were short shows that the tall parent must be heterozygous for tallness i.e. Tt. Therefore, the genetic make-up of the tall parent can be depicted as TtWW.
