Abstract
A Robertsonian pattern exists with a constant arm number of 72, and total chromosome numbers ranging from 53 to 60. Robertsonian differences exist between cells within individuals, and in modal counts between individuals. A modal count of 57 with 15 two- arm chromosomes was found in cell cultures from specimens from West Grant Lake in Maine, USA, while a modal count of 56 with 16 two-arm chromosomes was obtained for specimens from Lake Memphremagog on the Vermont USA-Quebec Canada border. Other studies on this species have largely been with the sea-run variety.
