Abstract

Cytogenetic analyses showed that a trisomic male brook trout of genotype BB'B'' for one of the lactate dehydrogenase subunit loci had a karyotype with two extra arms appearing as a metacentric chromosome. The metacentric chromosome probably arose through centric fusion of two acrocentric or telocentric chromosomes-one of which carried the locus for subunit B-followed by nondisjunction.
