Which of the following statements about double-crossovers are true? Please select all that apply.

Question

Quizplus · Accepted Answer

The further apart two loci are on a chromosome, the more likely they are to have one (or multiple) crossovers between them. Double-crossovers between two loci are not recognized as crossovers, which leads to an underestimation of the recombination rate between two loci. The map distance between two loci is related to recombination frequency (1% recombination = 1 map unit), so if recombination rate is underestimated then map distance is also underestimated. The probability of two crossovers occurring between two loci is lower than the probability of a single crossover occurring between the same two loci.
