Karyotypes of Cyprinus carpio and Leuciscus cephalus.

Karyological investigations on the common carp (Cyprinus carpio) and chub (Leuciscus cephalus) are described. The diploid chromosome complement in the carp was found to be 98, with 50 meta- to submetacentric chromosomes, 48 subtelo- to telocentric chromosomes, and an arm number of 148. Chromosomal studies on the chub revealed the diploid chromosome complement to be 50, with 34 meta- to submetacentric chromosomes, 16 subtelo- to telocentric chromosomes, and an arm number of 84.
