snpMatrix package is quite nice (read.plink())
Maybe glmer(cbind(abnormal, normal) ~ treatment*genotype + (1|batch), data=x, family=binomial())
Sewall Wright used an ordinal model for toes, IIRC ;). It might be more stable. Cheers, David Duffy,

In finadata.txt. you have ANIMID 3178 in twice, once as offspring of 1156 and 3104, and later as offspring of 1156 and 3065 (mergped as only the latter).

You need to provide boring details like "sessionInfo()" on old and new machines, so we can see which versions of the packages you actually have installed, and whether your locale is weird...

I have not done any comparisons versus other programs, but: https://mran.microsoft.com/package/HMMEsolver where the algorithm is described in Kim (2017) A Fast Algorithm for Solving Henderson's Mixed Model Equation https://arxiv.org/pdf/1710.09663
