Thank you for visiting nature.

Dioecy, the presence of separate sexes on distinct individuals, has evolved repeatedly in multiple plant lineages. However, the specific mechanisms by which sex systems evolve and their commonalities among plant species remain poorly understood. With both XY and ZW sex systems, the family Salicaceae provides a system to uncover the evolutionary forces driving sex chromosome turnovers. In this study, we performed a genome-wide association study to characterize sex determination in two Populus species, P. Our results reveal an XY system of sex determination on chromosome 14 of P. We further assembled the corresponding sex-determination regions, and found that their sex chromosome turnovers may be driven by the repeated translocations of a Helitron -like transposon.

John William Money 8 July — 7 July [1] was a New Zealand American psychologist, sexologist and professor at Johns Hopkins University known for his research on human sexual behavior and gender. Believing that gender identity was malleable within the first two years of life, Money advocated for the surgical "normalization" of the genitalia of intersex infants. Money introduced new terminology in sex research, coining the terms gender role and sexual orientation. Since the s, Money's work and research has been subject to significant academic and public scrutiny. David Reimer lived a troubled life, ending with his suicide at 38; his brother died of an overdose at age He screened adult patients for two years prior to granting them a medical transition, and believed sex roles should be de-stereotyped, so that masculine women would be less likely to desire transition. Money's writing has been translated into many languages and includes around 2, articles, books, chapters and reviews. He received around 65 honors, awards and degrees in his lifetime. Author Janet Frame attended some of Money's classes at the University of Otago, as part of her teacher training. Frame was attracted to Money, and eager to please him. Money became a professor of pediatrics and medical psychology at Johns Hopkins University from until his death. Money proposed and developed several theories related to the topics of gender identity and gender roles , and coined terms like gender role [25] and lovemap. He popularised the term paraphilia appearing in the DSM-III , which would later replace perversions and introduced the term sexual orientation in place of sexual preference , arguing that attraction is not necessarily a matter of free choice.

Federal government websites often end in. The site is secure. Part of the rationale for this change was to move away from associations with gender, and to increase clarity by grounding the classification system in genetics. While the medical community has largely accepted the move, some individuals from intersex activist communities have condemned it. Alternative social and historical definitions of intersex — such as those proposed by the intersex activists — have the potential to do more justice to the lived experience of those affected by such classifications and their consequences. The classification of bodily variations is a complex, messy process. Classifications of variations of sex characteristics, or intersex traits, have changed significantly throughout history.

The genetics of sex determination in Nasonia vitripennis. As a major class of DNA transposons, Helitrons are hypothesized to transpose by a rolling circle replication mechanism, and have been found to frequently capture genes or gene fragments and move them around the genome, which is believed to be important in the evolution of host genomes Morgante et al.

Sex determination compared in Drosophila and Caenorhabditis. Cline, T W. The connection of the Y chromosome with maleness and masculinity led to associations with what were considered masculine traits, including aggression.

Our results reveal an XY system of sex determination on chromosome 14 of P. The Y was now firmly established as active, determinative, and indeed the marker of male sex.
