Recombination of 2 Genes Separated by 66 Map Units

[Suraj M]

Homework Statement

What is the percentage of recombination of two genes separated by 66 map units?

2. Relevant equation

3. The Attempt at a Solution
Maybe there appears to be no linkage? I don't know, by simple substitution it would be 66%.
I don't think that's correct. I mean the book says its not 66%.
Just wanted an opinion. Thank you

Recombination between two genes will be observed only if there are an odd number of crossover events between the two genes (https://en.wikipedia.org/wiki/Centimorgan#Relation_to_the_probability_of_recombination), so you also have to consider multiple crossover events.

I haven't learned about these topics in so much detail. What we've been taught is just that (% of recombination = distance in centimorgans)
With reference to that we were given this question, how do we solve it then?
