In a previous paper we demonstrated how the number of possible genotypic as
signments consistent with the rules of Mendelian genetics and with any know
n phenotypes could be calculated for an arbitrary genealogy. Here, we prese
nt further results for several regular genealogies constructed according to
some specified recursive formulae and for which the growth of the genotypi
c statespace, with increasing genealogical size, can be described by a line
ar system.
