Give the experimental verification of the chromosomal theory of inheritance.
Briefly mention the contribution of $T.H.$ Morgan in genetics.
Morgan used organism in him experiment.
The person famous for experimental genetics
Mendel's work remain unrecognized for long time due to
$I.$ Communication was not easy
$II.$ Concept of factors which did not blend was not accepted
$III.$ Use of mathematics to explain biological problem was unacceptable
$IV.$ He could not provide any physical proof for the existence of factors Choose the right combination
