First, with the Bearded Iris (excluding for the moment Arils, Regalias, &Psamiris, which are also Bearded Iris and closely related to what most consider to be the "true" Bearded Iris) there are two basic numbers of chromosomes.  One is 8 and one is 12.  Some species (all are dwarf I believe) have a basic set of 8 chromosomes.  Most species have a basic set of 12.  This is one set only; this is the haploid number, and you might consider it as the lowest number you can get in those species, the basic building block.  This is the number that is passed on to an ovule or pollen grain (gametes) when it comes from a diploid plant (read on).


Thanks, Dave,

Yours is one of the easiest to understand explanations I have seen.
