genotype.names provides the names of all possible genotypes in the
order required by the NOIA model (Alvarez-Castro and Carlborg 2007). The codes for the genotypes are
stored in the vector genotypesNames.genNames(nloc = 2)
genNamesAppend(name)genNamesAppend is an internal function and is not supposed to
be called by anything else than genNames. The names of the genotypes are stored in the vector
genotypesNames. By default, they are "1", "2", and
"3", the heterozygotes being "2". The genotypes at different loci
are then put together, such as "123" for 3 loci.
