Another question for Hempcat, and others...
I posted this on a strain thread...
I've just gotten a couple SLH beans for the next run, and reading this thread I have a question...
How is it that one particular strain (in this case SLH) can have pheno's that are both indica dom and sativa dom? Wouldn't dominance run thru the strain? I've only read a little about breeding but I don't remember reading that a stabilized strain would produce pheno's with varying dominance.
Any input?
Picked this information up in biology.
Basically genes are either dominant or recessive. When two organisms breed the deck is shuffled so to speak and the outcome is somewhat uniform in the sense that the plants are basically the same if they are the same phenotype. If they are not the same phenotype however, the differences can be dramatic.
The chart below explains it somewhat...
(The chart is not coming out right so just move the top R r over a little and you can see how the link up)
R r
R RR Rr
r Rr rr
Basically as you can see there are similarities in all 4 of the possible phenotypes. The fact they are "R" When compared closer we see there are some that are a pure breed, or hybrid (the "RR" and "rr") which when breed with the same offspring ("RR" with "RR" or "rr" with "rr") will always produce this result. And then there are the more common phenotypes which contain both genes and when breed can produce any number of results.
To put it into layman's terms:
The seeds you are growing have not been hybridized to the point that you will get only one phenotype every time. As far as I know guaranteeing this 100% is impossible. But each time you make a new generation of hybrid seeds you further increase the odds of getting a plant with those same traits.
Similar to that of humans. Both my parents have brown eyes and brown hair. My brother and I on the other hand have blue eyes and blonde hair. The odds of this happening 2 times from the same parents such as mine is very slim. Simply because the blue eye gene as well as the blonde hair gene are both recessive genes.
If I were to mate with a female with the same recessive genes present the chance to have a child with the same traits would be further increased.
If I were to do the same with a female carrying the dominant brown or black hair color gene the chance decreases.
Hope that helps
