The book I mentioned has a large appendix on this subject, but focusing
more on whether the variation observed was as should be expected.
They come out very strongly in support of Mendel as a careful scientist,
as examined with the chi-square test (the test that the master statistician,
R. A. Fisher, used to question Mendel's results in 1936). Their position
is that his reputation has been restored in the last decade or two.
I recommend their book highly.
My question has more to do with me not really understanding how frequent
crossing over must occur.

I didn't realize that linkage could be so easily disrupted.
