polyploidy

Wikipedia: > Polyploidy has come to be understood as quite common in plants—with estimates ranging from 47% to 100% of flowering plants and extant ferns having derived from ancient polyploidy.

Instead of functional genes, the vast expanse of DNA is dominated by polyploidy and non-coding repetitive elements.

Remember though that the polyploidy in plants is a fundamentally different process from the way animals speciate.

But it's my impression that there's been massive breeding, induction of polyploidy, etc, etc.

If I take colchicine for gout is there an extra risk of polyploidy in my little swimmers?

It depends of the species, but polyploidy is common in plants because plants often can work as colonial organisms that can clone itselves.

I opened the article expecting to read about its use in plant breeding: colchicine is renowned there for inducing polyploidy.

This polyploidy constraint only exists for animal cells, not for plant cells.

We touched on polyploidy in genetics of course but I don't recall anything that was particularly salient insofar as resistances.

Another helpful technique for stimulating genetic changes is colchicine, which induces polyploidy.

This is good for avoiding polyploidy, but bad for fertility -- it is not necessarily the case that even one sperm will make it.

Yes, polyploid plants are generally healthier, because plants expect polyploidy.

But even without polyploidy, plants have large amounts of "specialized-use" genetic material, libraries of specific responses (e.g.

The problem animal cells have with polyploidy, is seemingly that it makes their cells physically larger — and in so doing, causes biological architectural assumptions like "blood cells can travel through narrow capillaries to deliver oxygen to cells within extremity tissues" to just fail to hold.

If some genes for oxidative phosphorylation must be physically associated with a certain unit area of bioenergetic membranes, then beyond that threshold prokaryotes could not maintain membrane potential homeostasis unless additional genomes are co-localized with the membranes." In re: 2, "The main difference between endosymbiosis and polyploidy relates to the size and distribution of genomes over evolutionary time.
