Gamete frequencies for all possible disomic and polysomic segregation
patterns for even ploidies 2 through 20. If you need higher ploidy levels,
let me know and I'll update it (it's very easy).

datasets

Provides tests for segregation distortion in F1
polyploid populations under different assumptions of meiosis.
These tests can account for double reduction, partial preferential pairing,
and genotype uncertainty through the use of genotype likelihoods.
Parallelization support is provided. Details of these methods are
described in Gerard et al. (2025a) <doi:10.1007/s00122-025-04816-z>
and Gerard et al. (2025b) <doi:10.1101/2025.06.23.661114>.
