There is little doubt that hostas are ancient amphidiploids. Bet Ben
doesn't know what an amphidiploid is. However, since they behave like
diploids (Ben - that's why they are called amdipdiploids) and there
are no 30 chromosome hostas, it is generally correct to call them
diploids. Amphidiploids also mean that most genes are duplicated.
This duplication of genes in an amphidiploid has significent
consequences as it can make it more difficult to get a recessive
phenotype, but it also allows for fixed heterozygosity which can be
beneficial.
