The results of the present investigation allowed the standardization of the first QFQ-banded karyotype of this species especially useful for identification of cattle chromosomes in gene mapping studies. sequential banding QFQ-banding RBA-banding I standardization cattle Resume - Application d une technique séquentielle de bandes QFQ-RBA aux chromosomes prométaphasiques bovins Bos taurus L . Une technique séquentielle de ban-des QFQ-RBA est presentee pour la premiere fois sur les chromosomes prométaphasiques bavins dans le but d etablir des correlations entre les bandes Q et R. Les résultats de la présente recherche ont permis 1 établissement du premier caryotype standard QFQ bovin au niveau prométaphasique utilisable pour la localisation des genes dans 1 espèce Bos taurus L. technique de bandes séquentielles bande Q bande R standardisation bovin Correspondence and reprints 386 D Di Berardino ei al INTRODUCTION Q-banding on chromosomes of cattle Bos taurus L has so far not received as much attention as the G- or the R-banding techniques. The lack of a standard Q-banded karyotype has been one of the major drawbacks which hampered the application of this technique for routine analysis of cattle chromosomes. More recently the utilization of Q-banding for chromosome identification in cattle gene mapping Fries et al 1989 .
