Polyploidy: Recent Trends and Future Perspectives - Tanvir-Ul

It is known in humans that even having 1 extra chromosome can cause severe damage (the only true survivable ones being Down syndome, and extra sex chromosomes). Human Reproduction vol.2 no.8 pp.721-727, 1987 Post-fertilization polyploidy in human preimplantation embryos fertilized in-vitro R.R.AngeU, A.T.Sumner1, J.D.West, S Strikingly, the ratios of nuclear polyploidy and multinucleation differ substantially among endotherm species . 39–41 Human adult cardiomyocytes mostly contain a single polyploid nucleus, while mouse cardiomyocytes are primarily multinucleated. 1,2 Other mammalian species, such as rabbits and rats, exhibit predominantly binucleated hearts, 39,40 and the porcine heart is heavily Polyploidy plays a significant and fascinating role in cultivating plants today. To those of you who still aren't familiar with this, it is a feature where the organism has more than two copies of each of its chromosomes.

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. Chromosomal analysis from aborted tissue has become an important diagnostic aid. However, the necessary cultures are frequently unsuccessful due to the condition of the aborted tissue.

Polyploidization is well tolerated in many species and can lead to specific biological 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.
