Abstract
The nuclear DNA content of all diploid poeciliid fishes known to date ranges from 1.30 to 1.92 pg, and is thus lower than the median amount for fishes in general, and teleost fishes in particular (2.0 pg). As is expected, triploid forms of Poecilia and Poeciliopsis have half again as much nuclear DNA as diploid forms. Unisexual forms of the two genera tend to have slightly less nuclear DNA than the amount expected if compared with their gonochoristic progenitors.
