【 摘 要 】

Chromosome characteristics of Peranakan Etawa (PE) goat needs to be analyzed because information about Indonesian goat races is very limited. The purpose of this research was to determine the characteristics of PE goat chromosome as basic data as one of the genetic local resources. Blood was collected from pair of PE goat at Sumber Sekar Field Laboratory, Faculty of Animal Husbandry, Brawijaya University, Malang. Blood cultured using standard cytogenetic technique and stained with G-Banding. Observations being done in metaphase cells and analyzed using Genus Cytovision Image. Chromosomes arranged and numbered by standard goat karyotype. The result of this research showed that PE goat had number of chromosomes 2n=60, consisting of 29 pairs of autosome and a pair of sex chromosomes. Female goat had average of total length (TL) of autosome ranged from 47.91 μm±6.46 to 22.12 μm±3.33. TL of chromosome X are 45.96 μm±4,59 and 44.45 μm±3,96. Centromeric index (Ci) of chromosome X, 31,74 and 32,80. PE goat had average of TL of autosome ranged from 58.20μm±6.72 to 18.97μm±2.82. TL of chromosome X is 56,42μm±7,38 and Y chromosome is 15,80 μm±3,24. Ci in chromosome X and Y are 19.34 and 46.84. These results concluded that the total of goat chromosome was 60 with types of autosomal chromosomes were acrocentric as many as 58 chromosomes and pair of sex chromosomes XX and XY, X classified as subtelocentric and Y submetacentric.
