different species Polyploidy has its own drawbacks too – the resulting plant could be weak or sterile. Especially, induced polyploidy is thought to be unstable and results in weaker plants. The success of polyploidy depends on many factors; from the process through which polyploidy has occurred, to which genes are being expressed and inherited. Polyploidy, recognized by multiple copies of the haploid chromosome number, has been described in plants, insects, and in mammalian cells such as, the platelet precursors, the megakaryocytes. Several of these cell types reach high ploidy via a different cell cycle. Megakaryocytes undergo an endomito … This is found in the Autumn Crocus and is an anti-inflammatory used to treat Gout in humans.

Reference: 1. Griffiths, Anthony JF. 2013-12-05 · Humans, like all other animals and most eukaryotes, are diploid: we have two matching sets of chromosomes, 2 x 23 = 46. Polyploidy means having 'many' ('poly-') sets of chromosomes, more than regular diplody. In other words, 3 or more sets of chromosomes, up to 6 or more in some plants and fungi. True polyploidy is vary rare in humans. 1977-07-26 · Rapid determination of polyploidy in human chorionic tissue sections. Riekki K, Baillie JE, Nair KK, Dill FJ, Poland BJ, Baillie DL.
