For linked genes A, B, and C, the map distance A–B is 5 map units and the map distance B–C is 25 map units. If there are 10 double crossover events out of 1000 offspring, what is the interference?

You observe 5 double crossovers among 100 test-cross progeny, or 5%. If the two single-crossover frequencies are 0.2 and 0.35, what is the coefficient of coincidence (c)?

Assuming the DNA of an organism contains equal amounts of A, T, C, and G (25% each), how often would the restriction site GATC be expected in the genome? HINT: What is the probability that a nucleotide at one site on a chromosome will be a G? Same question for an A, a T, and a C.
