Who constructed the first genetic map based of the fruit fly

Who constructed the first genetic map based of the fruit fly X chromosome based upon genetic crosses in 1931? Who were they a student of? In a 3 point test cross: How do you determine the order of loci for a 3 point test cross? How do you determine which progeny represent non-recombinant, single crossover recombinant, or double crossover recombinant progeny? How do you determine where the crossover occurs in single crossover recombinant progeny? How do you calculate the distance between each pair of loci? How do you calculate the coefficient of coincidence and interference? For a chi-square test of independence: What is the null hypothesis? How do you construct a contingency table? How do you calculate the expected numbers for each phenotypic class of progeny? How do you calculate chi-square, degrees of freedom, and P-value? How do you determine if the genes are independent or linked?

Solution

Alfred Sturtevant, an American geneticist constructed the first genetic map.

He was the student of Thomas Hunt Morgan. Throughout his career he worked on the organism Drosophila melanogaster with Thomas Hunt Morgan.
