换一批摘要Well-spread meiotic pachytene bivalents were obtained by using the prolonged hypotonic treatment com-bined with high chloroform Carnory's fixative solution from cells of the testes of domestic pigs. Comparisonin the division index and length of pachytenc bivalents with metaphase chromosomes showed that those ofthe former are 5 times higher and 3.42(1.87-5.98) times longer than those of the latter. Comparative studieson chromomere maps of bivalents and mitotic chromosomal G-bands were conducted by using the chromo-some 12 as a example. Sex vesicle and various shapes of synaptic sex chromosomes have been observed.Two-color PRimed IN Situ (PRINS) labeling has been conducted successfully on pachytene bivalents of pigs.
