offspring_gf_2

Calculates offspring genotype frequencies under the two-parameter model.

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>.
