Chromosomal localization of two Z chromosome-specific DNA fragments (DZGif1 and DZGif2) in Japanese quail

摘要

Two genomic DNA fragments of Japanese quail, DZGif1 and DZGif2, were isolated as DNA sequences with difference of copy numbers between males and females in a previous study. We have determined the chromosomal locations of these DNA fragments by fluorescence in situ hybridization. DZGif1 and DZGif2 were localized to q1.1->q1.2 proximal end and q1.5->q1.6 of the Z chromosome, respectively. These fragments are the first random genomic DNA markers mapped to the Z chromosome in Japanese quail, and they would be useful for constructing the genome map of Japanese quail.
