MCQ

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:

Options

  • TTWW

  • TTww

  • TtWW

  • TtWw

Solution

TtWW

Explanation:

It's possible that TtWW is caused by the parent's genes. Half of the offspring are short, which means that the parent plant will also have some short genes. All of the offspring had violet flowers, which is more evidence that violet is more common than white.
