摘要

本通讯描述了一个自发三倍体的情况下，在中国的Aldrichina grahami(蛱蝶科:双翅目)。二倍体补体由2n=12个染色体组成，其中5对常染色体和1对远心性染色体(女性为XX，男性为XY)，而三倍体个体的补体中有18条染色体，15条常染色体和1条XXY性染色体。

Spontaneous triploidy in the blow-fly Aldrichina grahami (Aldrich) (Calliphoridae: Diptera)

The present communication describes a case of spontaneous triploidy in Aldrichina grahami (Calliphoridae: Diptera). The diploid complement consists of 2n=12, with five pairs of meta/submetacentric autosomes and a pair of telocentric sex chromosomes (XX in females and XY in males), while the triploid individuals revealed eighteen chromosomes with fifteen autosomes and an XXY sex chromosomes in their complement.
