Chromosome Analysis of the Domestic Goat using High-Resolution Chromosome G-banding Technique

Abstract

Chromosomes of domestic goat (Capra hircus) were analized in detail by high-resolution chromosome G-banding technique and studied the efficiency of this analysis. The results obtained were as follows: 1) It was compared with chromosomes in metaphase and prophase by G-banding technique. Number of all bands in haproid set were recognized 206 bands at mid metaphase (MM), 269 bands at early metaphase (EM) and 353 bands at pro metaphase (PM). 2) Percentages of chromosomes length in each stages were measured 141% at EM and 156% at PM that values obtained at MM were expressed as 100%. 3) Chromosome No. 1, 7 and X were observed that banding patterns among each stages were small differentation. 4) Chromosomes at late prophase were not able to harvest. From the above facts, it was harvested more clearly karyotype on high-resolution chromosome G-banding pattern than chromosome G-banding pattern at metaphase. We supposed that it came effect for identification of chromosomes and some genetic analyses.
