Nepenthes without identification


Recommended Posts

what is a reverse cross?

Well, when you cross two plant and you get seeds from it. This seeds are the F1-generation. When you cross seeds from the F1-generation you are able to get a small amount of seeds that have the same genes than one of the parents.

A better explenation you can find in wikipedia.

Or he means someting like chance the male and the female parent. Something like ventricos x alata and alata x ventricosa....

A reverse cross is when you swap the sex of the parents.

ie N x wrigleyana = N.mirabilis x N.hookeriana.....first name being the female or seed parent, second being the pollen parent.

N x coccinea = N.hookeriana x N.mirabilis the reverse of the above.

It is clear from this that if one has a hybrid that the labelling must always be written female first to correctly identify it.

That's imposible.. :woot: You will never get the same genes of the parents...Do you know what is the chromosome crossing?

Thank you Dicon for the explanation!(I didn't know you could get different characteristics if you swap pollen doing the right cross or the reverse one)

PD: Of course wasted, ladies always first! LoL!

Also, if its an x. wrigleyana or x. coccinea then one of its parents is a hybrid in the first place ( x. hookeriana) so theres a lot of variability all along the way..

I see... :woot:
