| Abstract: | The chromosomes of taenia hydatigena in Guangzhou was studied mainly by the air-drying technigue of the gonadal tissue and a simple cell cultivation method in vitro. The chromosome number of this tapeworm was n= 9 , 2n = 18. The karyotypes consisted of 1 pair of large submetacentric, 7 pairs of medium metacentric and 1 pair of telocentris. Meiosis is a lengthy process, its first stage, prophase I, is particularly complex, commonly subdivided into five subs-tages: leptonema, pachynema,zygonema, diplonema and diakinesis. Figures 1-8 show the micrographs of prophase I of meiosis in taenia hydatigena. |
