This function creates an inheritance cube to model a MEDEA drive system. This system was first discovered in flour beetles. It biases inheritance by expressing a maternal toxin such that offspring die unless they express a zygotic antidote. This drive has 3 alleles at 1 locus:
W: Wild-type allele
M: MEDEA allele
R: Resistance allele
