A big thank-you to all of you who responded with such succinct info re
'ploidy'. I've had quite a bit of experience, genetically, with certain
mutations of the gouldian finch (Chloeiba gouldiae), but never had to wonder
if any progeny were a 'grex' or whether their chromosome
pairing/distribution represented genotypic 'mules'. Alleles and loci seem
pretty mild compared to orchid pollen!

Thanks again.
