You are mapping the location of two genes in Drosophila, listless l and blind b. (l+ l+ b+ b+) and (l+ l b+ b) flies are normal, but (l l b b) flies don't move around very much and cannot detect the location of a light source. You perform a testcross with a doubly heterozygous fruit fly and get the following results:listless, sighted: 100 listless, blind: 400 normal activity, sighted 400 normal activity, blind 100 What is the distance between these two genes?
