Enabling pleiotropy #58
Description
With RangeShifter 3.0 and the rework of genetics, pleiotropy is no longer possible. Two traits may use the same positions in the genome, but the mutation and expression of their alleles are resolved independently. The only effect of this genetic overlap will be genetic linkage between the two traits.
Pleiotropy may be desirable, and may not be too complicated to implement - this is to be considered.
