Figure 1. Distribution of T. dalmanni CGH log₂ ratio values.

Male and female genomic DNA were hybridized to microarray slides containing probes designed from EST sequence data. A total of 3444 genes are represented. The large peak indicates autosomal genes while the smaller peak are genes on the X chromosome. Dark bars indicate the log₂ ratio distribution for all the genes, while the hatched bars provide the log₂ ratio distribution for the 132 genes that violate the syntenic relationship between the X chromosome in T. dalmanni and the 2L chromosome in D. melanogaster.
