calc_Lstar

Calculate the reduced chromosome length that will give the target
expected number of chiasmata when conditioning on there being at
least one chiasma on the four-strand bundle.

utilities

Simulate and plot general experimental crosses. The focus is on simulating genotypes with an aim towards flexibility rather than speed. Meiosis is simulated following the Stahl model, in which chiasma locations are the superposition of two processes: a proportion p coming from a process exhibiting no interference, and the remainder coming from a process following the chi-square model.
