I know this is NCERT ques n its available on meritnation bt i dnt find full n gud ans der so pls help me out n ans of di ques plsss.............
Is there any difference between heredity and inheritance?
Explain with an example evolution through artificial selection.
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
