	Review
	Review Are homologies in vertebrate sex determination due to shared ancestry or to limited options? Jennifer A Marshall Graves, Catherine L Peichel Genome Biology 2010, 11:205 (30 April 2010) Abstract \| Full text \| PDF \| PubMed \| Cited on BioMed Central \| Editor’s summary The bewildering array of different sex-determination systems in vertebrates is built on a common set of genes and chromosomes.
