You're right about the S1 part, they will not be exact copies. But a cut from a plant is a cut from a plant, it is the same plant. If the part of the plant you took a cut from mutates, then the genetic material can be different. But you are not ever changing the genetics simply by cutting the plant.Did you know that even a clone doesn't give you an identical copy of the mother? It is damn near close, but still falsehood. Environment effects expression, period.
Sorry, end-rant. I just had oral surgery and am in mad pain.
This is all just from what I have learned and what I was taught. Could be totally fkn wrong for all I know.
Point being that if you get a clone from a plant you won't get an IDENTICAL copy if you run it (especially if it came from another room). And it WILL have different expressions under different environmental conditions, not can.You're right about the S1 part, they will not be exact copies.

Now on the other hand, a genotype can express differently under different environmental conditions. This would mean you have a different phenotype of the exact same plant, which is possible. This is called epigenetic variation, a genes expression can change over time. If the conditions in which you are growing highly favor a certain trait, it is possibly a cutting line can start to naturally grow that way. This is much much much much more common with woody plants that have been growing under certain conditions for a very long time, but it is possible. http://blogs.discovermagazine.com/8...f-two-trees-epigenetics-makes-clones-diverge/
See, this kinda implies I was spreading the wrong information. My point was your not going to get the same bud floating in the clinics from a clone, that's all. Just because you get a cut, doesn't mean it will be IDENTICAL to the mother (emphasis on IDENTICAL).Mushin-
No dick measuring, just trying to spread the right info here. Clones are exact genetic copies of the plant they were taken from. Genetic mutation is the only way the genetic information can change. Expression can change under different circumstances, and under certain environments the expression WILL definitely change.
When I run the same clone a few runs in the same room, I get the same bud every harvest. Small differences, but no more than two different strains.
See, people can still be reasonable and cordial on the Internet. :) You being the more civil of us two, lol.Mushin-
Semantics, exactly! You are right, if you buy a clone from a club, you are only buying the possibility of getting that exact bud. But as a exact genetic copy, you have a very high possibility of achieving that.
I only comment because I don't want people to see that and think clones are no good, and they need to buy seeds every time they harvest. They can clone their plants and grow out the same plant over and over. And in the same growroom, you are going to get pretty damn close to identical.
You were right, it is semantics on how your post is read.
The clone is an identical plant, the expressions may or may not be identical.
A "single cross" is another name for an F1 hybrid. When two IBLs are crossed the F1 hybrid, or single cross, is the result. This type of cross has the most uniformity and hybrid vigor.
A "double cross" is made by crossing two single crosses which come from four separate IBLs. A double cross will be somewhat more variable than a single cross, but will have a wider range of adaptability. This adaptability makes the double cross good for diverse environments.
The "top cross" and the "three way cross" are used as testers. A top cross is an IBL crossed with a variety, and it is used to test for general combining ability. A three way cross is an IBL crossed with an F1. The result of this cross will be one of the parents of the double-cross, and it is used to test for specific combining ability.
A "backcross" is crossing the progeny back to one of its parents,and on another level, to any plant with the same genotype as a Parent. It is designed to improve the parent by retaining most of its qualities and adding a new one. After a series of backcrosses,some degree of uniformity is realized as a result of increased gene frequencies,fixing of some loci through selection and some incidental homozygosity. However, the offspring can only become completely homozygous if the recurrent parent was completely homozygous,and will remain heterozygous for the loci that were heterozygous in the recurrent parent.
A "self cross" is the result of a female Cannabis plant pollinating herself, whether by artificial induction or natural hermaphrodite tendencies. A female that has produced seed from its own pollen is said to be the S0 generation and the resulting seeds are the S1 progeny.
A "full sib" cross is a straight male-female cross between brothers and sisters.
A "half sib" cross uses sister females and unrelated males.
Isn't that a thing?
What about gibberellic acid? Isn't that also used to reverse cannabis?
Awesome post! Can you post a link for the website?Neither a breeder nor pollen chucker, I'm a humble seed maker, but I dont seem to see a concise answer to the thread...
S1: The first selfed generation.
F1: the first cross between two unrelated parents. The F stands for filial, and refers to the fact that all F1 progeny of the same cross are full brothers and sisters to one another.
F2: the second cross between two of those F1 plants.

If you took something to F6, and decided it was finished it would become P1
then using it in a new cross you'd go back to the top of the chart again...
say you took it to F4
then hit one it with one of the original parent plants...
hit that with its parent again...
S1 hit with pollen from its parent = S2
Parent hit with S1 pollen = S1BC1 or S1Bx1... I have also seen it written as SB1
