An excess of gene expression divergence on the X chromosome in Drosophila embryos: implications for the faster-X hypothesis.
The X chromosome is present as a single copy in the heterogametic sex, and this hemizygosity is expected to drive unusual patterns of evolution on the X relative to the autosomes. For example, the hemizgosity of the X may lead to a lower chromosomal effective population size compared to the autosome...
