I gather itβs an βerrorβ in metaphase? The chromosomes fail to separate properly?
Edit: I just realised that citations and formatting didn't carry through from my post on r/microgrowery. Should be fixed now
Hi all, I came across this article that discusses the merits of induced polyploidy, suggesting that it will be the next greatest revolution in cannabis cultivation since GM seeds.
##What is polyploidy Basically, polyploidy is a mutation that causes a plant such as cannabis to produce huge (massive) buds, eg. this. It occurs naturally, but can also be induced chemically. Colchicine is a medicinal substance used to treat gout and other such diseases. It also inhibits chromosome separation during cell division. This causes a duplication of the cells chromosomes. Treating a seed to induce this mutation is called induced polyploidy.
##How Two studies 1 2 both find that the optimal treatment for this is submerging the seed in a 0.2% colchicine solution for 24h before proceeding with germination. Any longer, may damage or kill the seed.
Now for a little biology revision. A regular cell is a diploid, meaning it has has two homologous (identical) sets of chromosomes. A mixoploid is an organism that has an unequal set of chromosomes in adjacent cells. A tetraploid contains four sets of chromosomes. Both studies also agree that mixoploid plants resulting from this treatment contain greater concentration of THC and produce larger flowers. However, tetraploid mutation may actually decrease THC content relative to diploid (regular) cannabis. This is why we should remove the seeds after only 24h.
The studies found that this mutation may slow down initial plant growth. This can be combatted by growing a 'sea of green', using more plants and flowering much earlier. This in theory should produce a literal canopy of bud.
##BuT mUh CheMiCaLs Colchicine is not toxic to humans at reasonable doses, hence why it is used a medical treatment. Small quantities are only used when the plant is a seed, and there is no evidence that it magically finds its way up to the bud, especia

I'm gonna start this off by saying that I will probably use some words in a weird way since idk any terminology in english. I know that polyploidy occurs in certain species naturally, but some sterile hybrid species of plants in agriculture have been treated with colchicine and boom bam, they're no longer infertile due to an even number of chromosomes. What would happen if a person/fetus became polyploidic as a result of some mad experiment? Could they live? Would they be able to have children and if so, then what happens? I'm merely a high school graduate so i know nothing but I'm interested.
Since I last posted I've been doing some more reading and watching and I think the idea that Adam and Eve were polyploid is good. I already read Dr. John Sanford's book Genetic Entropy, Dr. Nathaniel Jeanson's book Replacing Darwin, and Dr. Michael Behe's book Darwin Devolves, and now I've read more papers and some of Dr. Rob Carter's videos and some other videos on youtube.
I like the idea of created heterozygosity to explain all the differences in people but I don't think Dr. Jeanson and Dr. Carter did a good job answering some questions. I don't think the recombination rate is fast enough even if you start with thousands of differences in Adam and Eve.
But if Adam and Eve start with a lot of chromosomes then the recombination rate doesn't matter. Plants are polyploid all the time. Even some animals are still polyploid. There are fish that are 3n and 5n and some rotifers are 4n. So I think other animals being created polyploid is possible.
I think the important thing is that Dr. Sanford and Dr. Behe are right about how things break down over time. We are losing genes every generation because we have so many mutations, and even good mutations break things. So over lots of time we lost a lot of chromosomes. And now we can only be diploid. But in the past I think we had more and that's where all the differences come from.
So I think being created polyploid solves the problems with created heterozygosity not being fast enough and it also fits with genetic entropy. What does everyone think? I know there are some evolutionists here. Do evolutionists think this could work?
Anyone know if it's possible to induce pollen sacs on a tetraploid cannabis plant? If I use colchicine and get a tetra, can I then clone it and use colloidial silver on it's clones to get tetra seeds?
Why does polyploidy give plants an advantage but animals a disadvantage?
