Weed is an amazing plant. I enjoy talking about it... :lol:

Weed was once a Perennial plant and then switched to annual. Not often done. It's like a gumby plant.

Two from one: new research maps out evolution of genders from hermaphroditic ancestors

November 20th, 2008 Research from the University of Pittsburgh published in the Nov. 20 edition of Heredity could finally provide evidence of the first stages of the evolution of separate sexes, a theory that holds that males and females developed from hermaphroditic ancestors. These early stages are not completely understood because the majority of animal species developed into the arguably less titillating separate-sex state too long ago for scientists to observe the transition. (in the first cross, that works out to 1/3 male. 1/3 female, and 1/3 sterile. There can be variances, but usually it will break down this way)

However, Tia-Lynn Ashman, a plant evolutionary ecologist in the Department of Biological Sciences in Pitt's School of Arts and Sciences, documented early separate-sex evolution in a wild strawberry species still transitioning from hermaphroditism. These findings also apply to animals (via the unified theory) and provide the first evidence in support of the theory that the establishment of separate sexes stemmed from a genetic mutation in hermaphroditic genes that led to male and female sex chromosomes. With the ability to breed but spared the inbred defects of hermaphrodites, the separate sexes flourished.
"This is an important test of the theory of the early stages of sex chromosome evolution and part of the process of understanding the way we are today," Ashman said. She added that the study also shows that plants can lend insight into animal and human evolution. "We have the opportunity to observe the evolution of sex chromosomes in plants because that development is more recent. We wouldn't see this in animals because the sex chromosomes developed so long ago. Instead, we can study a species that is in that early stage now and apply it to animals based on the unified theory that animal and plant biology often overlaps."
Ashman reported in Science in 2004 that animals and flowering plants employ similar reproductive strategies to increase reproductive success and genetic diversity. These methods include large numbers of sperm cells in males, mate competition and attraction through fighting or natural ornamentation, aversion to inbreeding, and the male inclination to sire as many offspring as possible.
For the current study, Ashman and Pitt postdoctoral research associate Rachel Spigler worked with a wild strawberry species in which the evolution of separate sexes is not complete, so hermaphrodites exist among male and female plants. Sex chromosomes in these plants have two loci—or positions of genes on a chromosome—one that controls sterility and fertility in males and the other in females. Offspring that inherit both fertility versions are hemaphrodites capable of self-breeding. Plants that possess one fertility and one sterility version become either male or female. Those with both sterility versions are completely sterile, cannot reproduce, and, thus, die out.

Offspring that inherit both fertility versions are hemaphrodites capable of self-breeding. Plants that possess one fertility and one sterility version become either male or female. Those with both sterility versions are completely sterile, cannot reproduce, and, thus, die out.
The single-sex plants breed not only with one another but also with hermaphroditic plants and pass on the mutation, which can result in single-sex offspring. (Sterile plants also can result, but plants with genes that favor the production of fertile offspring will be more successful.) When inbreeding depression in hermaphrodites is also considered, Ashman said, a gradual decline in the number of hermaphroditic plants is to be expected. Consequently, fewer chromosomes with both fertility versions of the loci will be passed on and the frequency of single-sex individuals will increase.

was hermies heard of in the old days of panama red and ty sticks and accupulco gold

or is it recent like femanized plant time

im starting to hate femanized plants had a nurvana snow white and a dutch passion bluberry running side by side the bb start looking weird to me in week 6 of flower it hermed dont knw why no clue

snow white a beautiful tough strong plant lots of frost and big buds it also was a fem

but im looking down the road and see some lumps in the road later

i dont know if the world really needed fem seeds we got them now

peace my brothers grow good

I read an article once. I wish I could rember the source, but they were syaing that there is a small area in Spain which has a microclimate and there are big perennials to this day.

I think it has always been there. I have considered the fact that as growers we get rid of the males and basically set up harems of females. I think it is possible that the lack of males may induce a hermie.... nature is funny.... and life will out. :peace:

There is no gender breakdown for Hermies. It is a "trait", not a sex. I believe the Hermie trait is existent in all weed. The trait comes out when stress is sensed as a survival technique
Click to expand...
.I'm hypothesizing here, but plants that herm easily likely do it because of an ethylene uptake ?'disability'? of some sort.. Whether we call it a trait or a gender is a moot point, because gender is actually a trait itself, and its much more complex than XX/XY in reality (even in humans at times as that runner controversy shows).. Granted for the sake of not convoluting BS, I agree that sex should be a separate entity since we typically describe traits as things that could express in either sex..
Anyways wiki actually has some cool info on cannabis sex determination.. http://en.wikipedia.org/wiki/Cannabis#Mechanisms_of_sex_determination
I think it would probably be more accurate to say that herming is the result of a trait more than a trait itself

Yes, actually i typed it backwards... hermie isn't a sex,,, it's a trait.. sometimes I'm thinking too far ahead of my typing... :lol:

I'll take a look. I'd love a definitive answer on whatever is scientifically known. Almost anytime you google hermie,,, all sorts of threads pop up with curse words.... :mrgreen:

How stoned are you? You typed it correctly the first time, and again the second.. :) I was just mincing words..
Theres not much definitive in the wiki, but it does portray the diversity that has been responsibly studied..

when u say selective breeding do u mean x breeding with another strain? What I am really trying to ask is this. Will every seed from a hermie then go on to produce plants that will produce seeds that will produce plants that in all likely hood have the same chance/ratio of being hermie as the seed i started with? Or will some be obviously hermie, some female(with hermie traits) and some male(with hermie traits). Am i not understanding the science?
Click to expand...

every seed from a hermi plant will have a higher chance of produceing more hermis, and every generation after has an even higher chance.

the chance of producing seperately sexed plants is less and less with each generation regardless of the pressence of stress conditions

a hermi can be male with fem flower or

femi with male flower... although fems with pollen seems more common

Sorry---Books tend only to be accurate when all variables are exact and known, The NL you have may be close to an IBL but chances are its not so the 1/3--1/3--1/3 is off. Way to many uncontrollable variables to come up with exact ratio's but your going to have a large population of femmed seeds with the possibility of a hermi trait"NOT A PROBLEM" the product REVERSE from DUTCH MASTER works great---foliar on day 3 and then again on Day 10 of flowering and you'll have no problems. _____________________________KEEP GROWING BROTHER...

Yes, I have thought about that as well. I have a hermie going right now.....it hermied late in the flowering and I have separated it and will grow out the seed this year and record all of the results. It's not scientific, but I think a general idea can be gleamed from it. If I end up with 50 seed, I will plant them all.

Its also worth noting that some equatorial strains are pretty damned near monocious.. True sativas can really add alot of hassle to a grow, but if you're willing to bear it, then thats a euphoric high!

Edit: Regardless of accuracy across the genetics board, I like the 1/3 breakdown as far as general info goes.. Its a good realistic warning to beginners who want to play with hermie shit.. Beyond that though, the ratio of male:female, and the point in the timeline when herms tend to pop staminate flowers are definately aspects to be considered..

so would it be better to use the seeds from the selfed hermi or would the seeds from the females that the hermi pollinated be better?

Or even better, a plant that has been tested, and stress tested and did not herm at all under those conditions, then was forced to herm via chemical application such as giberellic acid, or ionic silver which forcefully disrupt ethylene pathways forcing any otherwise stable plant to produce pollen.. Thats how the most responsible feminized seeds are created.. The effort is in the testing to ensure the plant doesn't herm without chemical intervention..

nonesense.....unless the principles that Ashman explains do not apply to cannabis. Are Ashmans' findings/conclusions bullshit?
