Chromosome painting is one of the effective methods in studying the evolution of genomes. The chromosomes of the species of fishes--M. aculeatus, M. albus and D. rerio were painted respectively with human X and Y chromosome-specific DNA probes. The results showed that some homologous segments of human X chromosome were found in the genomes of all the three kind of fishes, all the segments were scattered on several pairs of homologous chromosomes in each kind of fish. But no homologous segment of the human Y chromosome was found.
染色体涂染是研究基因组进化的有效方法之一。分别用人X和Y染色体特异性DNA探针涂染了鱼类物种——刺鳅、白鲢和斑马鱼的染色体。结果表明，在这三种鱼类的基因组中均发现了人类X染色体的一些同源片段，所有片段分散在每种鱼的几对同源染色体上。但未发现人类Y染色体的同源片段。
