NettetUltimately, it took a young undergraduate student and an “all-nighter” to mathematically elucidate the problem of linkage and recombination. In 1913, Alfred Sturtevant, a student in Morgan’s laboratory, gathered results from researchers in the laboratory, and took them home one night to mull them over. NettetGenetic Crosses Involving Linkage While linked genes don’t independently assort, they canseparate from one another. This separation happens because of crossing over during Prophase 1 of meiosis. To understand this, we need to see what happens in crosses that involve linked genes.
