| Popis: | Representative samples of Portuguese cattle from Barrosg, Maronesa, and Mirandesa breeds underwent cytogenetic investigation. Banding showed that 134 (65.0 %) Barrosas, 74 (40.2 %) Maronesas and 4 (1.6 %) Mirandesas carried rob (1;29). "be frequency of this translocation in the three breeds (39 % in Barrosas, 23 % in Maronesas, and I % in Mirandesas) was in a genetic Hardy-Weinberg equilibrium for the three karyological forms (2n = 60, 2n = 59 and 2n = 58), strongly supporting the hypothesis for an ancient origin of this translocation and the hypothesis of the origin of Maronesas from BarrosP and Mirandesa cross-breeding.
