摘要
采用常规细胞遗传学手段，对青海省畜牧兽医科学院饲养的哈白兔×日本大耳兔Ｆ１的染色体核型进行分析，结果表明，Ｆ１的染色体数目２ｎ＝４４，染色体臂数ＮＦ＝７８（♂）；常染色体类型１～７对为中着丝粒染色体（Ｍ），８～１０对为亚中着丝粒染色体（ＳＭ），１１～１６对为近端着丝粒染色体（ＳＴ），１７～２１对为端着丝粒染色体（Ｔ），性染色体Ｘ为亚中着丝粒染色体（ＳＭ），Ｙ为中着丝粒染色体（Ｍ），公兔核型式为４４，ＸＹ（♂）。
The chromosome karyotype of HabaiJapanese large ears rabbit F1 rearing in Qinghai Academy of Animal and Veterinary Science were studied by conventional cytogenetics technique.The results showed as follows:The chromosome number of F1 was 2n=44 and classified 22 pairs,its total chromosome arms number(NF) was 78;Among the 21 pairs autosomes,the shape type of 17 pairs were metacentric (M),810 pairs were submetacentric (SM),1116 pairs were subtelocentric (ST) and 1721 pairs were acrocentric (T).In the 1 pair of sex chromosomes,the chromosome was submetacentric and the Y chromosome was metacentric.The chromsome karyotype of male rabbit was 44,Y.
