Origine paterna del cromosoma sessuale X in una Trottatrice Italiana a cariotipo 63,X

Abstract

In questo lavoro si riporta un nuovo caso di cariotipo 63,X in una cavalla e si stabilisce, per la prima volta in questa specie, l’origine parentale dell’unico cromosoma X presente nell’assetto cromosomico dell’animale portatore. L’analisi citogenetica eseguita su 100 metafasi, trattate con colorazione Giemsa, bandeggio CBG e sottoposte alla tecnica di ibridazione in situ, eviden- zia un cariotipo 2n=63,X escludendo una condizione di mosaicismo; l’origine paterna del- l’unico cromosoma X presente è stata stabilita tramite analisi di due microsatelliti altamente informativi: LEX024 e LEX003.

In this work, we report information about a new case of a 63,X chromosome constitution in a mare and we established, for the first time in this specie, the parental origin of the only X chromosome present. The cytogenetic analysis of 100 metaphases, using both Giemsa staining, CBG banding and FISH technique, shown a 2n=63,X condition with no sign of mosaicism, while paternal origin of the only X chromosome present was ascertained analysing two high informative microsatellites: LEX024 and LEX003.
