No, not usually however, that said, some can be depending on the genetics. Maybe one of our scientific minded members can give you specifics. There are lots of hybrids and they cross with other specie orchids as well as with other hybrids to create new hybrids.

Orchids generally appear in 3 catagories. To make it simple......
species are... diploid..2 lots of chromesomes.
Hybrids can be...diploid, 2 lots of chromesomes and labelled 2n...tetraploid, 4 lots of chromesomes and labelled 4n...and triploid, 3 lots of chromesomes and labelled 3n.
The plants marked 4n and 2n are breeding plants, the 3n are not. Depending on the orchid, its not always possible to tell if it will breed. The above is mainly used for Cymbidiums but are also appearing in Vanda etc, Dendrobium, Cattleya and a few other orchids.

so basically, since it is intergeneric or interspecific hybridization, if both parents are have the same number of chromosomes, it wont be sterile; and if there is a differnce, it would be sterile. thanks.

so, one thing comes into my mind... single cross hybridization... parents are the same species/subspecies, like what traits or alleles can be dominant (or recessive). i have read a thread here about single crossing a white catt. assuming we use different plants, what traits/alleles of the offspring or its filial generations could be different from the parent (e.i. shape, color, scent)?

Are there any site to check the N#?

No site for this. You have to rely on the label and seller/breeders honesty.
