摘要: 对猪巨吻棘头虫成虫的卵细胞染色体进行了观察,其染色体为6对(2n=12,n=6)。其中大型中部着丝粒染色体1对,中型中部着丝粒染色体3对,小型亚端着丝粒染色体1对和小型端部着丝粒染色体1对。

Abstract: The chromosomes of adult M. hirudinaceus ovary specimens were studied. The chromosome number was found to be 2n=12, n=6. The ovariogenic tissues which consisted of one pair of large metacentric, three pairs of medium metacentric, one pair of medium submetacentric and one pair of small telocentric. Six bivalents (n = 6) were found in the primary oocytes.
