Re: polyploidy (Lach)

it is found in some insects, amphibians, reptiles, and most commonly in plants as you mentioned...it was not thought to exist in mammals...

however, nature (23 september 1999) has an article on the discovery in argentina of a tetraploid rat apparently found in the wild and not produced in the lab like the mice that amaranth refers to below...they appear to be unaffected by the phenomenon

there is also a very recent article on lab mice whose placenta was derived from tetraploid host cells that may be related to the work amaranth mentions below...nature 415:1035 (28 Feb 2002)
