C99 seedling has a "secondary plant" growing near its stem?

Hi Betterhaff, they're called Rootrainers, made in UK by a couple of different companies, available in Europe to some extent too and thanks to google i now know they're made in canada too. http://www.rootrainersinternational.com/roottindex.html

I like using them but tbh I won't be buying any more - they're not cheap and they are really very flimsy, great design but the plastic they use splits so easily that you have to be really careful handling and storing them if you want them to last longer than a season. Hope that helps.

I acquired a bunch of these a few years ago.
I find that a dozen or so fit perfectly in a milk crate.
They are kinda flimsy so the crate adds tons of support.
Only thing I don't really care for is they're a taller than my planting trowel but that's really a non issue.

Thanks English Cut, good to know. I also like how deep they are, too bad about cost and durability.

This is true with haploids which have one set of chromosomes but not diploids which have 2 copies of each basically, in general, diploids are identical to the parent, but haploids are not..hence gametophytic apomixis
Peace

Apomixis is the asexual formation of seed without meiosis or fertilization. It is correct to assume the offspring will be genetically alike to each other and the parent. It is prevalent in some flowering species but I don't think cannabis is one of them.

More likely, the twins are either maternal (identical) or paternal, created thru sexual reproduction. Maternal twins occur when the zygote splits before mitosis forming 2 embryos. Paternal twins happen when 2 female ovules (gametes) are fertilized by separate male gametes. To have paternal twins in plants the separate embryos would share a common seed coat.

You are correct though, the offspring of a diploid that under goes apomixis will be identical to the parent. But offspring of a diploid that reproduces sexually will have corresponding genes (provided by haploid gametes) from each parent therefore will be a combination of both and not unique to either.

Sorry BBB, didn't mean to sidetrack your thread. How's the runt?

No worries on the side-tracking.

Very interesting conversation happening, I am soaking up

The runt is still runty but to my surprise, even though the "main plant" has steadily grown, gotten more bushy and is now more or less completely covering the runty twin, the runt has actually further developed its leaflets and looks to be pushing a second node of leafs.

Still very small but considering the circumstances, I am surprised he/she has healthy looking, albeit super tiny, leafs!
