A complex chromosomal polymorphism in Gobius fallax (Gobiidae, Perciformes)

Abstract:

Chromosome analysis of 53 specimens from a population of Gobius fallax has revealed inter- and intra-individual variation in the diploid number (2n=38–43) arising mainly through Robertsonian translocations. The presence of a small biarmed chromosome in a few cells from 3 males as well as the numerous multivalent configurations in meiotic plates and the apparent association between the NOR-chromosomes and other acrocentrics suggest that this polymorphism has an inherited as well as a somatic origin and that some translocations may involve more than two acrocentric pairs simultaneously.
