Cytogenetic observations on a Robertsonian translocation in Saanen goats

A Robertsonian translocation of submetacentric type was detected in a herd of 15 goats of the Saanen breed, reared on a farm located in southern Italy. Four males out of 5, and 2 females out of 10 were found to be carriers of the same translocation in the heterozygous state. All carriers were phenot...

Description
Summary:A Robertsonian translocation of submetacentric type was detected in a herd of 15 goats of the Saanen breed, reared on a farm located in southern Italy. Four males out of 5, and 2 females out of 10 were found to be carriers of the same translocation in the heterozygous state. All carriers were phenotypically normal. The RBA banding pattern demonstrated that the centric fusion took place between chromosomes 6 and 15 of the RBA-banded karyotype recently proposed as "standard" for the species Capra hircus L. The C-banding pattern showed the presence of 2 blocks of constitutive heterochromatin, corresponding to the centromeres of the 2 chromosomes involved in the fusion. Silver staining revealed telomeric nucleolus organizer regions on the long arm of the two-armed chromosome.
