The below mentioned article provides a short note on the Coupling and Repulsion Hypothesis of Gene. Bateson and Punnett in 1906, described a cross in sweat pea, where failure of gene pairs to assort independently was exhibited. Plants of a sweat pea variety having blue flower (BB) and long pollen (LL) were crossed with those of another variety having red [...]
