红鳍笛鲷(Lutjanus erythopterus)的核型研究
Study on the Karyotype in the Lutjanus erythopterus
【摘要】 以红鳍笛鲷为材料 ,取头肾经空气干燥制片法制片 .经过姬姆萨染色和核型分析 ,结果表明红鳍笛鲷的核型为 2n =4 8、4 8t,臂数NF =4 8.
【Abstract】 The karyotypes of Lutjanus erythopterus were examined from their renal tissues by PHA injection_air drying method.Giemsa stain and observation of chromosome spreads under the microscope. The results showed that there are 48 acrocentric chromosomes in diploid and its karyotype formulae is 2 n =48 t,NF=48.
