The organism with the highest chromosome number recorded in to date is estimated to be 1,440 (or 720 pairs) found in the adder’s tongue fern Ophioglossum reticulatum.

A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.

To date, the organism with the least number of chromosomes is the male Australian ant, Myrmecia pilosula, with one chromosome per cell (male ants are generally haploid—that is, they have half the number of normal chromosomes while the female ant has two chromosomes per cell).

And now it has been seen in people. In a recent article, a doctor in China has identified a man who has 44 chromosomes instead of the usual 46. Except for his different number of chromosomes, this man is perfectly normal in every measurable way.
