Sex Determination in Plants:
In most plants, male and female reproductive organs are found in the same flower (bisexual or hermaphrodite plants), or in different flowers of the same plant (monoecious plants, e.g., maize, castor, coconut etc.). But in some crops (e.g. papaya, asparagus etc.) and several other plant species, male and female flowers are produced on different plants (dioecious plants).
The mechanisms of sex determination in plants are essentially similar to those found in animals. One extensively-investigated case of chromosomal sexuality is known is plants, i.e., in the genus Melandrium of family Caryophyllaceae. Here the Y chromosome determines a tendency to maleness just as it does in humans male plants are heterogemetic (XY) where as female plants are homogemetic (XX). This system is the most common in plants.
Sex determination in some plant species e.g., papaya (Carica papaya), Spinach (Spinacea oleracea) Vitis cinerea, Asparagus etc, is postulated to be governed by a single gene. In papaya, a single gene with three alleles (m, M1 and M2) is suggested to control the sex differentiation. Female plants are homozygous mm, while male plants are heterozygous M2m; the heterozygote M2m produces hermaphrodite condition. Genotypes M1M1, M1M2 and M1M2 are inviable, i.e. M1 and M2 alleles are recessive lethals.
Maize plants are generally monoecious, i.e. both male and female flowers are produced on the same plant. A single recessive gene, ba (barren cob), interferes with the development of cobs (the female inflorescence) when this gene is in the homozygous state.
The cobs remain undeveloped in ba ba plants, making these plants functionally male. Another recessive gene, ts converts the male flowers in tassels of ts ts plants into female flowers. As a result, the tassels of ts ts plants do not produce pollen but they set seed; such plants are, therefore, functionally female. In plants homozygous for both ba and ts (baba tsts) the cobs are undeveloped and barren, but many seeds are produced in the tassel; such plants are thus functionally female.
Thus, two recessive genes (ba and ts) have converted a naturally monecious maize plant into a dioecious one. Other recessive genes affecting the development of male and female gametes are known in maize, e.g., ms (male sterility genes), male sterile cytoplasm (Cms) and sk (silkless gene causing ovule abortion) etc., and in many other crops."

Soooo does this mean sex is determined at time of conception or..........?

Lots of people say they get M:N ratio of male-female but they never seem to log every seed they pop, which is the only way to actually know. They're always going by memory and memory is a funny thing.
I have some Mothers Milk going right now. One is 4 weeks in and it has that powdered milk smell. I found a couple seeds in an amazing smelling bag of Lemon Thai Haze last year, one was male, and the other flowered with the same smell as this MM. I thought that the milk smell was such a huge letdown from the mother that I decided to not waste time running bag seeds anymore. Since this MM smells like it, I'm not impressed. I'm a long way from vaping it, though the lemon thai haze bagseed didn't get better with cure, and the others aren't far enough along to have any opinion.
Last round was Goji, 4 females out of 7 popped, one was super loud and strong while the other three were pretty average. Next Bodhi for me is SSDD then Blue Tara.

Oh and not to mention i get the same ratio from every strayfox pack ive ever popped too. And........ id say 90%+ of every seedling reguardless of breeder that i flower will pop a sac or 2 on lower preflowers in mid-late flower. Not talkin shit or blaming the breeders. I would love to find out this is environmental.Just reporting my findings. The clones of these seedlings rarely ever pop sacs, its just the seedlings. My environment is hardly ever perfect. Very dry here. But im no scientist nor geneticist. Just reporting my observations.
But it makes sense to me that a plant would rather be male if it lives in a dry environment. Pollen loves dry rh. Moisture kills it. I keep telling myself "well only time will tell". But as time goes by and ive still never had a female ratio above 50% from purchased seed packs (where the seeds were convieved in a different environment than my own). Mad coincidence? I guess so.

Does this mean I could request a pack of all females...and get only big hole girl beans? @strayfox gear

Hahaha i think that might be the first time someone ever requested big hole females. Usually they want small hole ones.
Anyhow, stray ill take a pack of big hole females too

I'd say from what we know about Animals and other plants that yes sex is determined at the time of seed conception. How else could we have feminized seeds? pollen determines sex, how? No clue, but from what we know about the feminization process alone negates anything that this temperature theory brings to the table.

I'd say this is a pretty accurate simplistic explanation of Cannabis judging from what I have experienced myself and have read about others experiencing.

Vader from Ocean Grown did a study of a bunch of seeds he popped to see if shape, stripe pattern, or hole size could be used to predict male or female. None of them were higher in one sex or the other. It was kind of interesting to watch, but it would have been a lot cooler if it workedHahaha i think that might be the first time someone ever requested big hole females.

They weren't even popped all at once. 3 here, 2 there.Outta the prob 2 dozen bodhiseeds packs ive popped, every single pack has 2-4 females regardless of the father. Never fails. Except 1 strain i got 7- barefoot dr. (Ssdd father).
The shit has me stumped. I mean i would understand if everyone else was gettin the same ratios, but theyre not. How have all 24+ seed packs have the same number of male/female? I cant help but hypothesize that sex expression is environmental. But then when i popped 17 of my ssdd f2s i made i got 15 females.....
Then my atf pack gave me 9 females.
Veg room never goes above 72 degrees.
Stumped as well.

Luckily I did take clones, and I've always gotten good results with all of Bohdi' s stuff and I've grown quite a few. I also have a few Oroblanco ready to go in so hopefully they do better.
Every time I come check on this thread it makes me wanna go order more seeds, especially when I find out Goji of won't ever be made again

this topic comes up alot. Prob because of me lol sry for being "that guy".
i experimented with changes to my veg room after id came across some info stating that cooler, more humid, less light (18/6 as opposed to 24/0) encouraged females. Didnt matter, still got same ratios. I ran the test on several seed packs of dif fathers over prob 6month span. Altho i will admit, i wasnt able to raise rh to where i would have liked, 65%-70%. Id be lucky to hit 50% some days. Everything else in the rm was and is normally tits, climate wise. Plants were showing no signs of stress either way, even with normal conditions of low rh, we're talkin prolly 30%rh average. No difference.
Good points. I think the science on the subject is pretty solid in favor of predetermined sex, and i want to agree. Ill admit i dont know. I have mad respect for the scientists making discovery and sharing it, explaining it. I guess what i mean is that i do believe the science, im just stumped as to why my actual experience differs somewhat. I was unable to change ratios w environment, in my case its low female 4:1 M:F ratio no matter what i do. Its possible that im just really unlucky. Dont wanna believe that one but maybe thats just the case lol. Not that it matters, i still find hella flame keepers in bodhiseeds packs, reguardless, im happy. I periodically clog the thead (apologies yall) w this same topic just to hear others experience and opinions. Mines still stumped, but when i pop 50 bodhi packs ill come back here w the results. Im still hoping the 1:1 ratio is true, bcuz if thats the case then i should have a shit ton of females comin lol.

Will you post the logs of, say, the last 100 seeds you popped? Just the name of the strain, the date planted/germed, date sexed, and the sex. You can put it up in a gist and put a link here or whatever. It would be very interesting to see what kind of ratio you really get. Even if its just the Bodhi seeds you popped, if you have logs for all of them then that would be very interesting.

Can't wait to see how ur orablanco turns out and yeah I'm glad I ordered a pack of the gogi og and the ssdd before they disappear

My Bodhi ASS at 19 days smelled like 3 yr old or better Cheddar. Very strong.
First plant I ever had that smelled like cheese. Appalachian Super Skunk!
Planted 4 seeds with sprouting roots Wednesday of The Fuzz but have only one up. Seems odd and probably something local here.
Thunder Wookie is potent and spacey, relaxing and more but will report in the future.
