Have you seen twins in a strain before?

[Fraktaal]

DigDugs And Jaws seeds are clearly conjoined seeds that grew together into a double seed. Normally we sort seeds like those out because they look abnormal. They are always two.

Often you can even break those double seeds in half and have two viable seeds.

Yep, not twins in the same sense that the others are.

They had twins like our a million years ago. That's just my opinion but evolution takes time.

Rarely do you see nature do something it hasn't done before. You may not have been around long enough to have seen it before is all. ;)

Rapid evolution (AKA contemporary evolution) can take place in just a few hundred generations under natural conditions. Inbreeding can increase the rate of mutations significantly.

That isn't evolution but it is true that plants adapt very quickly. We can breed for many traits and inbreeding can cause problems.

Don't know if anyone has tried to select for twins but they aren't a mutation.

I have tin sisters who seem pretty normal. Kinda bitchy though...;)

Contemporary evolution is evolution. Find me a single evolutionary biologist who disagrees with me.

There are studies which show that there is a genetic basis for fraternal twins. This means that is is possible for mutations to arise from inbreeding which increase the likelihood of twins being born. I'm not saying twins themselves are a mutation, but you can have mutations which increase the rate of twins in a given population.

Whatever...

The real question for me is whether there are 4 gametes involved as is normally the case with 2 seeds. If less than 4 than they are more "twin' than any two others seeds from separate calyxes (doesn't make them any more stable for breeding though).

Anyway, here's my recent double yolker, which is from a normal round seed, third this year (out of roughly 150 seeds). Just a small plastic cookie box with coco so was easy to look for shell, definitely came from a single seed.

First one shows how neatly they were folded:

I've seen it before but they never grew passed seedlings, i hope yours make it.

 

[Sativied]

I've had no problem with them yet except for one that had only 1 cotyledon, it's in post #15

They each have their own tap root so they can be easily separated and replanted and then there's no difference with a regular seedling.

I have one growing like this and one growing 2 seperate plants. Can they be both make and female? Since it's a cross I made can one side favor the mom and they other side favor the dad? The cross pictured is sleestack x kandy kush and the other not pictured is SoCal master kush/c 99 x kandy kush. I'm assuming the kandy kush male is causing the twins.

Are these 2 plants gonna be identical or will there be variation?
