    Why Didn't Mendel Use Cannabis?

    Because he needed a PEE...

    Clickbait, sure but admit it, you did at least crack a smile.

    Why was the pea plant used in Mendel’s experiments?

    Mendel picked pea plants in his experiments because the pea plant has different observable traits. It can be grown easily in large numbers and its reproduction can be manipulated. Also, pea has both male and female reproductive organs, so they can self-pollinate as well as cross-pollinate.

      hairyman he's got to be a scientist formost in genetics.

    I'm researching/deciphering the following genetic information for accuracy:

    " Breeding and inheritance in F1 Fast Version® strains

    For the development of the F1 Fast Version® genetics we use the best selected autoflowering strains and the collection of elite clones from the Sweet Seeds® bank of mothers.

    The autoflowering or photoperiod trait is dependent on a single gene. This gene presents two possible alleles. One is dominant (F), which is the one that codifies the photoperiod character while the other one is recessive (a) and is the one that codifies the autoflowering character. As the allele that codifies the autoflowering character is recessive, to express this type of flowering it is required to be in a state of homozygosis, which means that all the autoflowering plants are (aa), as they have received a gene (a) from the father and another one from the mother.

    On the other hand, every photoperiod strains (elite clones) of the Sweet Seeds® bank of mothers that we use to produce F1 Fast Version® strains are homozygotic for the dominant character that expresses the photoperiod-dependent flowering. They are (FF) as they have received a (F) gene from the father and another one from the mother and this is something that we can deduce from the analysis of the offspring of these clones.

    The first resulting generation of the cross between these two types of strains –photoperiod (FF) and autoflowering (aa) –, obeying to the first Mendel Law or to the Hybrids Uniformity Law for the first filial generation, provides as a result a 100% of hybrid specimens (Fa) and as (a) is recessive and (F) is dominant, 100% of the population is photoperiod dependent and zero autoflowering plants show up. This first hybrid generation between homozygotes for one or multiple characters in the genetic line is known as F1 Hybrid.

    As it refers to a F1 seed, if we cross these seeds (Fa) with each other to obtain more seeds, then the second generation, known as F2, concurring with the second Mendel Law or Character Segregation Law for the second filial generation, will not produce 100% Fast Version (Fa) specimens anymore. Within the specimens originated from this procedure, we would obtain a mix of 25% autoflowering (aa), 25% photoperiod (FF) and 50% Fast Version (Fa). The only generation that is 100% Fast Version (Fa) is the F1 Fast Version®."


    I grew F1 White Widow Fast Version last year as the female part x male part Passion No. 1.

    The resulting seeds are being used in this year's seed and bud crops and I decided it was about time I got my lazy arse into gear and found out at least the basics of genetics and possible outcomes of this year's seed-growing experiment. The Basics

    I'm 68 and they say, "you can't teach an old dog new tricks".

    Well, I'm going to prove that statement wrong...

    Mendel's Law or Character Segregation Law for the second filial generation is surprisingly fascinating once you get a simple explanation.

    I'm slowly working through the laws and it might take a while. But, the growing season is long and I literally have nothing else going on.

    ​Happy days

        Hello There,

        Well, I did wade through the Basics.

        It was a hard slog but not a complete waste of time. Because with the knowledge gained, I can form better search strings targeting cannabis and hybridisation.

        So, I kicked back and rolled a stubby using White Widow bud and Passion No. 1 dry sift 120-micron hash to get that short-lived clarity of thought before the giggles and munchies begin.

        The first search returned this link at the top of the listings.

        How Modern Genetics Influences Cannabis Strains

        (don't click the link yet)

        The page opens an article. It contains a summary about crossing Sativa with Indica, with all the keywords highlighted using bold text.

        Remember, I'm in a hyper-alert state of mind.

        Something felt odd and yet familiar about the way the page was formatted. H1 heading, H2 heading in paragraph titles and the bold text used to highlight keywords, multiple links to the company homepage with no links back to the article.

        I stumbled onto a webpage expertly crafted by a top Search Engine Optimisation company!

        The first giggle started and grew into a burst of uncontrollable laughter.

        They are using the same techniques as I did way back in 1994. It seems they still fool Google.

        I can recommend the SEO company.

        You can find their contact details by searching the author's name.

        Yesterday was happy stumbling.

        Today looks like being better.

          I thought I grew F1 White Widow Fast Version last year as the female part x male part Passion No. 1.

          It turns out that I had bought Fast White Widow from Seedsman and the seeds were photoperiod.

          This means the resulting F1 seeds harvested from last year's crossbreeding of Fast White Widow and Passion No. 1 are 100% regular photoperiod. Happy Days!


          ​White Widow is a hybrid strain that was created by crossing a Brazilian sativa strain with a South Indian indica strain. The exact genetics of the Brazilian and South Indian strains used in the creation of White Widow are not well documented, but it's believed that the Brazilian strain was a landrace sativa and the South Indian strain was an Afghani indica.

          Passion #1, on the other hand, is a pure indica strain that was created by breeding a Californian indica strain with a Mexican sativa strain. The exact genetics of these parent strains are also not well documented, but it's believed that the Californian indica strain may have been a Northern Lights strain or a related variety, while the Mexican sativa strain may have been a Haze or Skunk variety.​

          That heritage combined with the matching traits of each plant should provide some interesting effects, tastes and smells to sample in this year's F2 seed backcrossing.

          Pros and Cons of Using 1 Male with 1 Female or 3 Males with 2 Females When Crossbreeding F2 Cannabis Seeds

          When crossbreeding F2 cannabis seeds, there are pros and cons to using one male with one female or three males with two females:

          Using one male with one female:

          Pros:
          It's a simpler breeding process as there are only two plants involved.
          The offspring will be genetically uniform and have a higher chance of displaying the desired traits from the parent plants.

          Cons:
          It limits the genetic diversity of the offspring, which can hinder the creation of new and unique strains.
          It can be less efficient in terms of the time and resources needed to breed a large number of seeds.

          Using three males with two females:

          Pros:
          It can increase the genetic diversity of the offspring, which can result in a wider range of desirable traits.
          It can be more efficient in terms of the time and resources needed to breed a large number of seeds.

          Cons:
          It can be more complex, as there are multiple plants involved in the breeding process.
          It can be difficult to ensure that each male plant has equal representation in the offspring, which can result in the loss of desirable traits.

          In general, the use of multiple male plants with two female plants is often preferred in breeding programs, as it allows for greater genetic diversity and a wider range of desirable traits in the offspring. However, using one male with one female can still be an effective breeding method, particularly if the goal is to preserve the genetic traits of a particular strain or to create offspring with consistent and predictable traits.

          Ultimately, the choice of breeding method will depend on the specific goals of the breeding program, the available resources, and the genetic diversity of the parent plants.

          As you can see, I've chosen to use the 3 males with 2 females rather than use only 2 plants.

          I think my self-education in Mendel's Laws might pay off big time!

            The males have started busting pollen all over the place!

            Bang on schedule.

            I've put sandwich bags around the pollen sacs to try and save the pollen for later in the year to spot-pollinate any female plants that grow particularly well. This should strengthen the strain.

            Looking forward to the seed harvest, which should be around mid-April.

            Happy days,

            Jack
