Final map and Interference calculation

The distance from sc to v was 33 cm and the distance from v to s was 10 cm.

sc<-----33------>v<--10-->s

The probability of a double cross over is .33 x .10 = .033

The expected number of double cross overs = the probability of a double c/o times the total number =.033 x 1000 = 33.

The actual or observed number was 24

The coeficient of coincidence is the observed no./expected no.= 24/33 = 0.72727

The interference value is 1-coeficient of coincidence = 1-0.72727 = .272727...
