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 an essential role during normal development and could also contribute to human diseases. Polyploidy is the multiplication of number of chromosomal sets from 2n to 3n (triploidy), 4n (tetraploidy) and so on. It is quite common in plants, for example many crops like wheat or Brassica forms. It seems to be rarer in animals but still it is present among some amphibian species like Xenopus. 2017-02-27 2008-11-04 How to Download Notes in PDF from Solution Pharmacy Facebook Group Using Laptophttps://youtu.be/cE5MAt0J6hs Using Mobile https://youtu.be/ntzXKi2pA5UFree Mod Polyploidy in humans (?)

Polyploidy describes the case of a cell or an individual possessing entire extra sets of chromosomes. However, polyploidy is not common in mammals, and it is usually lethal when it occurs.

Polyploidy. Cells (and their owners) are polyploid if they contain more than two haploid (n) sets of chromosomes; that is, their chromosome number is some multiple of n greater than the 2n content of diploid cells.For example, triploid (3n) and tetraploid cell (4n) cells are polyploid.Polyploidy in plants. Polyploidy is very common in plants, especially in angiosperms.

Yet even the human lineage underwent polyploidy events. Humans were not simply created having 46 chromosomes. There is nothing to say that an organism or a set of organisms unable to tolerate almost all polyploid events are therefore unable to survive all polyploid events.
