Provides a suite of tests for segregation distortion in F1 polyploid populations (for now, just tetraploids). This is under different assumptions of meiosis. The main functions are:
bayes_men_g4(): Bayesian test for segregation distortion using known genotypes.bayes_men_gl4(): Bayesian test for segregation distortion using genotype likelihoods.lrt_men_g4(): Likelihood ratio test for segregation distortion using known genotypes.lrt_men_gl4(): Likelihood ratio test for segregation distortion using genotype likelihoods.offspring_gf_2(): Offspring genotype frequencies under the two parameter model of meiosis.offspring_gf_3(): Offspring genotype frequencies under the three parameter model of meiosis.simf1g(): Simulate genotypes from an F1 population of tetraploids.simf1gl(): Simulate genotype likelihoods from an F1 population of tetraploids.
Details of these methods may be found in Gerard et al. (2025).
