Inheritance In Seeds Question
- Thread starter Sam_Skunkman
- Start date
My thoughts...
I would have to say that the F1's would be somewhere in the middle taking after both the large seed plant and the small seeded plant, making medium seeds. But, I would say the F2's would be 25% small seeded, 25% large seeded, and 50% will be medium seeded...

Depends if small and large seeds are the same variety or a hybrid.
Ok, Ok, I reframe in thinking about Mendel.
G=genotype
One thing that I recall after scrawling diagram on a piece of paper (yep, I'm old school) is that the test cross results tell you the genotype of the unknown. If the results are all small seed progeny (in other words, all dominant phenotype), the unknown small seed F2 is likely to be homozygous (GG, in words, all dominant in genotype). If the results are half small and half large progeny (in other words, half dominant phenotypes), the unknown small seed is heterozygous (Gg, in other words, half-dominant, half recessive).
So, I think....the progeny of a test cross is the genotype of the unknown (#4)....yes?

In my experience seed size is relative to calyx size when pollinated, idk it seems like my early seeded ladies produce much smaller seed, as such I have been waiting later in flower to seed.
Might be flawed or lacking science but it's just what I've seen in my limited experience.
Ive got some sour bubble beans usually always fat and big got some tiny ones from small clones i pollinated.
I'm sure there is genetics involved but I think we can influence the size quite a bit.

Perhaps the smaller seed would have better chances of being eaten whole and passed out in shit, and maybe larger seeds more chance to be crushed? idk lol
Some have posted similar...
#4
It is dictated by number of pollenated pistils and nutrition level of plant and health f plant
more seeds little
less seeds big
more food big
less food little
less seeds more food huge
many seeds less food tiny
I think it can be different branch to branch too based on the same factors plus main branch with bigger colas would have the biggest seeds.

We do!
pretty basic all things use as little energy up as possible during reproduction.. a big fat seed's shell is spread thin,, the small one thick... afghan on average gets penetrated by water and germinates inside of 3 days something like haze small thicker shell takes like 4-5 plus days.. i am sure i am not the only one who has observed this.
I found this tidbit looking around...

Publishing in the Proceedings of the National Academy of Sciences, the team from the John Innes Centre, an institute of the BBSRC, demonstrated that the gene acts locally at the base of the growing seed. It produces an as yet unidentified mobile growth signal that determines final seed size. If the gene is turned off, smaller seeds are produced, but crucially if the gene is turned on at a higher level than normal, seeds a third larger in size and weight are produced. This is the first time such a reciprocal effect on seed size has been observed, and points to the fundamental importance of this gene in plant development.

" A KLU-induced increase in seed size leads to larger seedlings and higher relative oil content of the seeds. "
Interesting stuff

Hi guys
Hey Tony, that would be more of a gene regulation/environmental thing (which could be inheritable) and I think Sam was coming from a more genetic viewpoint.
I'm with Chimera on this. If you disregard non-heritable stuff, I think the forces molding the outcome are ranked so:
additive>dominance>epistasis>environmental switches
So, linear/additive/polygenic being the main factor, resulting in a normal distribution.

I smoke the crushed seed casing to give me an indication of the final product. Organic of course, I find feminized seed give me that certain up high, regardless of size. Whew!
