The Queensland fruit fly, Bactrocera tryoni, like the Mediterranean fruit fly, Ceratitis capitata, has a diploid complement of 12 chromosomes, including five pairs of autosomes and a XX/XY sex chromosome pair. Characteristic features of each chromosome are described. Chromosomal homology between B. tryoni and C. capitata has been determined by comparing chromosome banding pattern and in situ hybridisation of cloned genes to polytene chromosomes. Although the evidence indicates that a number of chromosomal inversions have occurred since the separation of the two species, synteny of the chromosomes appears to have been maintained.
昆士兰果蝇(Bactrocera tryoni)与地中海实蝇(Ceratitis capitata)一样,其二倍体染色体组由12条染色体组成,包括5对常染色体和一对XX/XY性染色体。文中描述了每条染色体的特征。通过比较染色体带型以及将克隆基因原位杂交到多线染色体上,已确定了昆士兰果蝇和地中海实蝇之间的染色体同源性。尽管有证据表明自这两个物种分离以来发生了一些染色体倒位,但染色体的同线性似乎仍得以维持。
