Around the beginning of the twentieth century, William Jasper Spillman, one of Washington State’s first faculty members, recognized that eastern Washington farmers were committed to lucrative wheat as their primary crop. Spillman experimented by crossing wheat varieties to find traits desirable for the Inland Northwest.
Variations didn’t appear in the first generation, but Spillman soon observed that the second generation of plants had combinations of the parents’ traits. He then applied a mathematical formula to predict inherited traits, to the benefit of the wheat farmers.
Many of us know the basics of this research from high school science: Gregor Mendel’s laws of inheritance, … » More …
