Much of the SNP software for estimating pairwise relatedness does not seem to entail options for estimating regression-based pairwise relatedness in haplodiploid species where, e.g., brother-sister relatedness is different to sister-brother relatedness. Goodnight's old Kinship program did this nicely where specific hypotheses could be assessed. Is there similar software for SNP data where biallelic loci range up into the 1000s. Any advice would be great!
