Abstract

We investigated the cytogenetic characteristics of Korean native goat(Capra hircus). Chromosome slides were prepared from peripheral blood cell cultures. GTG, GBG, RBG and CBG-banding techniques were employed on those slides. The high resolution karyotype of Korean native goat could be made with the incorporation of BrdU. Korean native goat has 60 chromosomes composed of 58 autosomes and XY or XX sex chromosomes. All of autosomes of Korean native goat were acrocentric chromosomes. X chromosome was submetacentric and Y chromosome was metacentric. The GTG, GBG and RBG-band patterns of Korean native goat were similar to those of other goats. CBG-band regions were distinct at the proximal portion of the long arms of all autosomes in Korean native goats. According to our investigation, there was no significant difference in chromosomal band patterns between Korean native goat and other goats. It might be necessary to use molecular genetic markers for clarifying the genetical characteristics of Korean native goat whose biological characteristics are not clearly defined.
