The first experiment on polygenic inheritance was demonstrated by Swedish Geneticist H. Nilsson - Ehle (1909) in wheat kernels. Kernel colour is controlled by two genes each with two alleles, one with red kernel colour was dominant to white. He crossed the two pure breeding wheat varieties dark red and a white.

And Institute for Biology, University of Oslo. An understanding of how genes can control quantitative traits emerged in 1908 from the work of the Swedish geneticist Nilsson-Ehle who studied quantitative traits in wheat. Using Mendel's methods, he mated pure-breeding red-kernel strains with pure-breeding white-kernel strains. Nilsson-Ehle (1908) obtained the first experimental proof of polygenic inheritance in case of kernel colour in wheat. The possible origin of polygenic inheritance is due to the duplication of a chromosome or its part, the increase in chromosomes number (Polyploidy) or the mutations producing genes having the similar effect. Nilsson-Ehle, crossed two varieties of wheat, red and white in colour and found that all the F 1 offsprings were intermediate between red and white i.e., light red colour, showing that red is incompletely dominant over white. When the F 1 hybrids were self-fertilized the F 2 progenies or offsprings showed a ratio of 15 red to 1 white.
