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 parent can be depicted as
(a) TTWW
(b) TTww
(c) TtWW
(d) TtWw

Correct answer – (c)

TtWW might be the tall parent’s genetic makeup. The parent plant must also have a collection of short genes because half of the progeny are short. Additionally, all of the progeny produced violet blooms, further indicating that violet colour predominates over white.
