All genes that have been coduplicated with dmrt1 are inactivated by mutations. Numbers on the right or at the bottom show the length of the sequences in base pairs. The region of kb between the two Olaflnk genes is the Y-specific region Fig.
Unlike the paired autosomes, in which each member normally carries alleles forms of the same genes, the paired sex chromosomes do not carry an identical complement of genetic information. This is called the haploid condition. London: Icon Books. Sexual differentiation humans Development of the reproductive system gonads Mesonephric duct Paramesonephric duct.

Bertrand, R. But the incubation of the eggs of the lizard Agama at a high temperature produces males. Archived from the original on And these genes did not just survive all that time in species that eventually evolved into humans. This disorder, also called adrenogenital syndrome AGSresults from a genetically caused deficiency of cortisol, a steroid hormone produced by the adrenal cortex.
Model for evolution of Y chromosomes and dosage compensation. The Olaflnk genes are delimiting the regions with homology. This is a pattern typical for pseudogenes.
