Cojoined seeds....

[TheForgotten]

Is this common?

I recently popped some Afghani seeds and when they sprouted one of them turned out to be two of them, a root from each end.

I split them, we'll see if they survive the operation....

Are they twins? Will they likely share traits?

 

[SeriouslySilly]

My understanding is that they would begin life genetically the same. Now the question is.. will they stay that way? I say “probably not.”

Plants adapt their genetics according to environmental issues/life experiences.
When you split them and escaped their inner tissue it activated their immune systems with a message to adapt, and the chances they both would have needed to adapt EXACTLY the same are slim -to-none, if only because there are so many micro-critters carried airborne that they likely had to adapt a little differently, even on a micro-minute scale.

That’s just my understanding from anecdotal observation of the same phenomenon you describe and reading a little science.
Somebody with deeper science knowledge probably will answer better.

Best regards.

“...*exposed (not “escaped”) their inner tissue”

Hi ,



that' s not so usual , but not so rare too ,


yes they are twins but usually in this case ,
you got one strong who finish like a " normal " plant ,
and one weak who grow less .


But you can grow the two and the weed will be similar ...

I probably overthought my original reply.

The two plants will actually be very similar, but the differences that do show will because of the situation I described in my too overthought reply, lol.

Yes and no. Just like human twins, they can be brother and sister. We hope not, but the possibility does exist.

Hi ,


you point something interresting !!!


The possibility is here ,
but personnaly never experienced it ,
certainly due to the fact i got twins only with fem seeds ,


is someone can talk a little more about experiment this ?


Really curious about

Did conjoined twins sprout from a single seed, or were two seeds conjoined?

I think that would make a big difference.

I've not seen identical twins, but have seen lots of none identical twins.

... single seed!

Looked like one at a glance, was 2 seeds cojoined....

I still ain’t understanding, but I ain’t a Rhodes Scholar, so misunderstanding should probably be expected from this one, lol.

If one seed produced two growing shoots they should be similar except for the environmental influence I babbled about in my first reply.

If two *mostly* separate seeds were conjoined, similarity probably shouldn’t be expected.

It depends on how the seedlings were created. From one embryo splitting into two ( and I don't know if that happens in seeds) or two separate haploid female cells meeting two grains of pollen, and a single shell forming around the pair of pairs.
