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 make-up of the tall parent can be depicted as

(a) TTWW
(b) TTww
(c) TtWW
(d) TtWw

Answer:

(c) TtWW

According to the law of dominance, Mendel showed that the one allele is dominant over the another one (expressed allele is known as dominant allele or unexpressed one is recessive). As shown in this question, the all progeny bears violet flowers but half of them are short, this means that the violet colour flowers are dominant and the dwarf flower which contains white flower is a recessive trait.
