Expression of Sox family genes in early lamprey development. Circular transcripts of the testis-determining gene Sry in adult mouse testis. Brain Res. Neuropsychopharmacology 32—
Martin J Lee BT. Foster, J. Chromosomal fissions are thought to be less common than simple chromosomal fusions, since each chromosomal fragment requires a centromere for proper segregation during meiosis. X-inactivation profile reveals extensive variability in X-linked gene expression in females.
Comparative sex chromosome genomics in snakes: differentiation, evolutionary strata, and lack of global dosage compensation. Non-homologous sex chromosomes of birds and snakes share repetitive sequences. Al Nadaf, S.
B Biol. Organizing action of prenatally administered testosterone propionate on the tissues mediating mating behavior in the female guinea pig. One encodes for a typical protein, the second results in a truncated protein, and third shows intron retention.

In those reptilian species that possess TSD, such American alligators, painted turtles and sea turtles, wnt11, cebpa, trpv4, sf1, wt1, dax1, dmrt1and sox9 may contribute to male gonad sexual differentiation Torres Maldonado et al.
The findings suggest genes residing on the sex chromosomes, other than Sry , might modulate sex differences in neurobehavioral patterns. The current brain transcriptome studies detected Zfy , but the gene and individual transcripts showed similar expression pattern in males and females.
Genome 12 , 17— Future studies should be directed at using transgenic mice and naturally occurring animal models lacking Sry to address this exciting possibility. Neonatal mice possessing an Sry transgene show a masculinized pattern of progesterone receptor expression in the brain independent of sex chromosome status.
