金乌贼染色体核型分析
Karyotype Analysis of Golden Cuttlefish Sepia esculenta
【摘要】 以金乌贼(Sepia esculenta)受精卵及发育的胚胎为材料,采用空气干燥法制备染色体。经Giemsa染色,镜检细胞分裂相。结果显示,金乌贼染色体数目2n=92,核型公式为2n=44m+32sm+10st+6t,染色体总臂数NF=168。
【Abstract】 The metaphase chromosomes of golden cuttlefish(Sepia esculenta) were prepared from the oosperm and embryo cells by air drying.The karyotype was analyzed.The results showed that there were 92 telocentric chromosomes and the karyotype was 2n = 44m + 32sm + 10st + 6t,NF = 168.
