The Study of G- Banding Chromosome in Silkie

오골계의 염색체 분염법 (G-banding)에 따른 핵형분석에 관한 연구

This experiment was carried out to identify the chromosomes of silkie. It was many difference from other breeds in morphology and characteristics. In this experiment, chromosomal analysis was used early embryos. In aspect of morphological chromosomes, chromosomal size and shape are similar to other breeds. The chromosomes of silkie were shown to morphlogy as follows. They were identified that chromosome #l and #2 were grouped as submentacentric, ＃3, ＃5 and ＃6 were telocentric ＃4 and ＃7 were acrocentric and ＃8 was metacentric chromosome. Zㆍsex chromosome was shown 5th, W-sex chromosome was 8th to 9th and they were metacentric chromosome, respectively. Each chromosome through the G-banding was shown the 3 dark bands in 1 p2, distinct light band in 1p1, dark band in 2p2, broad light band in 3pl, dark band from centromere and distal part in 4th chromosome and dark band in 5pl. Z-sex chromosome was shown dark at p-arm distal part.
