In Drоsоphilа fruit flies, the genes jv, st, аnd bw hаve been mapped tо the 4th chromosome. Their order and genetic distances are shown below. Suppose a 3-factor cross was performed with these three genes. Based on the indicated map distances, what is the expected frequency (rdouble) of the double crossover (DCO) class? [answer1] Suppose in the actual cross 9 DCO offspring were obtained out of 2000 total offspring. Calculate the amount of interference (I), if any, and input your answer here: [answer2]
