Relative sizes of the X and Y chromosomes in human ( H. sapiens ), mouse ( Mus musculus ), and fly ( D. melanogaster ). Drawn to scale. Gene counts are for protein-coding genes and do not reflect the number of copies in multi-copy genes. H. sapiens and M. musculus data obtained from Ensembl database release 73[91] and Pertile and Graham[96]. D. melanogaster X and Y chromosome size obtained from the literature[89, 90]. X chromosome gene count obtained from Ensembl database release 73[91]. Y chromosome gene count from the literature[89, 90].
