| 摘 要： | 采用淋巴细胞培养和染色体Ｃ─分带方法，测定了二花脸、大约克纯种猪Ｎｏ．１３和Ｎｏ．１６染色体Ｃ─带的长度、面积和异染色质的量，以图揭示家猪染色体Ｃ─带的品种差异．结果表明，二花脸、大约克纯种猪在Ｎｏ．１６染色体上Ｃ─带的长度、面积和异染色质的量存在着显著差异，以此可以作为区分两品种的重要依据．

| Abstract: | Lymphocyte culture and C-banding of chromosome of domestic pigs were carried out.The measurements of the length,area and heterochromatin quantity of C-bands were made of No.13 and No.16 chromosomes from the pure breeds Erhualian and Large Yorkshire with an attempt at revealing breed differences of chromosomal C-band of domestic pigs.The results showed that significant differences exist of the length,area and heterochromatin quantity of C-bands in chromosome No.16 between Erhualian and Large Yorkshire.These breed characteristics in C-bands provide important basis for distinguishing the two pig breeds. |
