In a cross between white-flowered parents, $F_1$ progeny was uniformly purple-flowered. The $F_2$ progeny showed a phenotypic ratio $9 : 7$ between purple-flowered and white-flowered plants. The above result indicates that the flower colour is controlled by
Mendel published his work on inheritance of characters in $1865$ but it remained unrecognised till $1900$ because
$(a)$ He could not provide any physical proof for the existence of factors
$(b)$ His concept of factors as stable, discrete units that controlled the expression of traits did not find acceptance from the contemporaries
$(c)$ Mendel's approach of using mathematics to explain biological phenomena was totally old
$(d)$ Communication was not easy (as it is now)
