Question

Evolution cannot be said to progress' from 'lower' forms to 'higher forms. Rather.
evolution seems to have given rise to more complex body designs even while the
simpler body designs continue to flourish.
• Study of the evolution of human beings indicates that all of us belong to a single
species that evolved in Africa and spread across the world in stages.
EXERCISES
1. 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) TIWW
(b) TIWw
(c) TWW
(d) TWW​
