hybrid question

[jeff1u]

hmmmm
guys have you thought of this question?

We normally put
species X * species Y = hybrid of XY

What happen if we put
hybrid XY * hybrid XY = ??

hybrid Z (hybrid XY x XY)

hybrid XY * hybrid XY = hybrid XY F2, assuming they are siblings in the first place. however some growers have reported F2 hybrids are very much weaker than the originals (thorelii x TM F2 comes to mind), probably due to the in-breeding?

[Aliamyz]

Will bring the same cross again but may differ in colouration because they are seed grown!

[jeff1u]

Hongrui, Hybrid F2 weaken? is there a reason to it?

[hongrui]

the reason, i think, is most likely due to inbreeding.

from wiki,
Inbreeding is breeding between close relatives, whether plants or animals. Inbreeding may result in a far higher phenotypic expression of deleterious recessive genes within a population than would normally be expected. As a result, first-generation inbred individuals are more likely to show physical and health defect.
