If the region between v-ct and ct-cv are acting independently, how many double crossovers would you expect in a population of 1448? How would you explain If you observed only 8 double crossovers in a population of 1448? 12, linked genes 12, interference 10, interference 10, linked genes SaveExplanation / Answer
Answer: 12, linked genes
Explanation:
Distance between the genes = (%) recombination frequency
Expected double crossovers (EDCO) = (Recombination frequency b/t v--ct) x (Recombination frequency b/t ct--cv) * Total progeny
EDCO = 6.4% x 13.2% *1448
= 0.064 * 0.132 * 1448
= 12
Obsereved double crossover frequency(ODCO) = 8
Coefficient of coincidence(COC) = EDCO / ODCO
= 8/12
= 0.67
Interference= 1-COC
= 1-0.67 = 0.33
