Some big claims there… We’ve mostly sequenced one cultivated clone-only and not anything else. And we basically have no idea what any of it means. The majority of the gene’s have not been mapped yet.
The cannabis male Y chromosome is actually larger than the X chromosome, not the reverse. A high-quality reference genome of wild Cannabis sativa | Horticulture Research.
If you’re saying the (most likely) functional data inside the chromosome, then sure, the X has more of what looks to be functional data than the Y does, but we still have no idea how or what either of those functions do.
We don’t even know if cannabis is x/y, x-to-autosome, or purely autosomal or what. There’s theories, most lately are leaning towards x-to-autosome. But we don’t know.
We do know there are X-linked traits, like the Freakshow line. That leaf trait is an X-linked recessive trait. So what traits could be linked to the Y?
I think that you misunderstood me. I was meaning to convey that the Y chromosome does have more over all data then X, but that both the autonome data and chromosome(the data within the chromosomes that are linked to sex) data is less and that the extra data of the Y is a repeatable pattern.
Sex traits in male plants often have to do with the antlers. This is very easy to observe in reversed plants where the female form antlers in “bud clusters”, while males usually form antlers in the “armpits”.
I’ve actually found out that there are A LOT of genetic data on cannabis. More then we publicly know. Most of it are held by companies in Israel and Italy. It would be super interesting to get to look at their research. It’s especially focused on cancer killing cannabis cultivars and in the search of understanding why it’s cancer killing and what the genetical difference are between cannabis cultivars.
that’s an awfully entitled way to look at the people paying their bills
the only problem I can see is if you intended to reintroduce males back into the line to make regular seeds again. Due to sex-limited, sex-linked, and sex-influenced genes, female plants could be carriers of deleterious genes that will only express themselves in their male progeny. BUT I’m going to go out on a limb and guess that it isn’t a big issue in reality. Just a guess
@ChongoBongo Yes, you are correct in a way! But this is a general problem with males and is not specific to female to female breeding.
The autonome data in the Y chromosome is only given
to males. This part of the dna is not passed down to females since only the X chromosome are passed down to the female progeny. So this data is only a concern for male progeny.
A sex linked trait in the autonomes can go by undetected if your progeny only consist of girls, and when you introduce a male into the mix, all male progeny down the line will either have suppressed traits so they can be hard to select or have enhanced traits, so they will look better then they are. But since its linked to the male sex, this is not something you will have issue with in the female side of the population, unless you intend to breed with the line. Then these sex linked suppressors/enhancers can make the selection work really hard.
This is one of the reasons why I chose female to female crosses when I made custom medicine when I was a caretaker. Males can fool you and when you have a very specific goal that is often the matter of someone’s health. You want to squeeze that time frame as short as possible. Now we are talking months to get to the point of success.
Some breeders have a longer time frame, let’s say 3+ years. Then having these type of problems with male progeny is not the end of the world and you start to know your work and cultivar in and out. Line breeding and continuous testing of progeny is crucial to keep the eye on the price, and not gamble too much.
thats not even a true statement. intersex plants and animals exist both as a cultral spectral and on a genetic level. its actually fairly common to have duplicate sets of sex chromosomes, there was even discussion of testing folks outta fear that extra genes would give them a competitive advantage
It’s a matter of semantic mostly but also from which border you’re talking.
The term “intersex” thinked in latin, atm, concern mammals and technically very specific cases unable to be translated in a generic binary system “intersex ON / intersex OFF”.
The political term is used to essentialize any artificial transition in something close to amphibians. I’m personally shocked by this approach, it’s quite insulting i find, but the first concerned look very comfortable with the idea so why not.
With cannabis … well … it’s fairly simple. It’s a fucking plant lol Monoecious VS Dioecious. It’s not linked with any feeling or whatever, so i don’t see any point to politize cannabis hermaphroditism.
Usually when reversed plant won’t drop pollen it’s cause either the concentration on STS is too high or you sprayed later into sac development and the plants not producing ethylene. A simple solution is to lay a banana (yes the fruit) at the base of the plant. It produces enough ethylene you should see more sacs open up.
so it would be more about to strong apposed to spraying to many time ?.
i usually spray three times, this last time i only sprayed once, got the same result’s. so do you think that would mean its to strong apposed to the # of times i sprayed them.
As @Fuel tried to tell you, I don’t think it wise to enter in this kind of debate. That’s a (wrong) opinion you should keep for yourself. Not the topic of this place anyway.
Best way to explain it and not get into organic chemistry is the silver plugs up the hole needed for ethylene production but breaks down after 4-5 days. Which is why you need multiple sprays spread over a period of weeks. That’s at the normal ppm which off the top of my head is like 200-250ppm. Increasing that doesn’t really speed things up but it can definitely slow them down since you need ethylene for the sacs to mature and drop pollen.
Measurements dates n all.
I personally use the popular 9:1 ratio but 4:1 works fine. Silver doesnt expire or burn plants.
To answer you.
No,
You’ll get as much seeds as a regular because one femmed clone is so a ton of pollen. And one female clone is no change or a given in math terms.
The only downside is more effort, maybe less diversity.
That’s it.
Extra chromosomes in cannabis is polyploidy.
Take the SD, this cut itself totally destroy any tentative to use a generic strategy. Just because the insane
ethylen levels of the cut itself are out of chart initially … it’s very much less generic to handle flawless rotations of a catalog.
For the doses and applications strategies : it doesn’t have any sense. If you produce your fems in a fast SOG with tiny donors dispatched, that’s absolutelty not the same deal that reversing a baobab in a greenhouse among others baobabs … i mean, just wtf. The kind of STS you’re using is important too, the hobbyist recipes are just a base. DP have a schedule for each single donor by example and the reversal process is fully automated. You can’t do it with a STS made in the kitchen.
