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
(c) TtWW
It is a case of test cross and it shows a genotypic ratio of 1:1 thus it should be heterozygous for Tallness.
TtWW (tall, violet) X ttww (short, white)

TtWw (tall, violet) |

Genotypic ratio: TtWw : ttWw = 1:1
Phenotypic ratio: Tall, Violet : Short, Violet = 1:1
There is no real progress in the idea of evolution. In terms of evolution, evolution causes generation of diversity and the . Due to evolution more and more complThat does not mean older and simpler body designs are inefficient and complex body designs like spiders, fish and chimpanzee have better body design. For example, bacteria are oldest and have simpler body design still survive. They are found in the most inhospitable habitats like hot springs, deep sea, the ice in Antarctica. So, bacteria, spiders, fish and chimpanzees are simply species in the teeming spectrum of evolving life. Thus, all the organisms which exist have a body design which is “better” as it is suited to their environment.
