摘　　要：采用骨髓细胞制片法对内蒙古地区胎生蜥蜴种群染色体组型进行研究,结果表明,其雄性二倍体染色体数为36,雌性二倍体染色体数为35,性别决定机制为ZZ/W型.除雌性性染色体为亚端部着丝点外,所有染色体均为端部着丝点,这与我国小兴安岭胎生蜥蜴种群的染色体组型一致,而与大兴安岭东坡的呼玛种群不同.The karyotpe of Lacerta vivipara from Inner Mongolia populations was studied by using medulla cells eolchicine - hypotonic air - drying technique. The results showed that in males, the number of diploidy chromosome of males was 36, while in females, they were 35, the sex determination mechanism depends on sex chromosomes. All of chromosomes of males and females are telocentric except for females＇ sub -telocentric sex chromosome. It is consistent with the most of Laeerta vivipara populations worldwide.
