Trends in Endocrinology & Metabolism, 1997
Recently, a number of genes have been identified that are associated with a failure of human sex determination, including WT1, DAX-1, SOX9, ATRX, and the Y-linked testis determination gene, SRY. Most cases of human sex reversal, XY females and XX males, do not, however, appear to be caused by mutations in these genes.

On the evolution of sex determination
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1987Abstract Female mice reject skin grafts from intrastrain males because of the H-Y transplantation antigen. Those females produce antibodies that recognize a male-specific cell-surface antigen in serological tests. The serological antigen has also been called ‘H-Y’, but there is evidence that the two antigens are distinct. We therefore

Sex Determination and Sex Chromosomes in Amphibia
Sexual Development, 2017Sex chromosomes in most amphibians are homomorphic (undifferentiated) in both sexes and are characterized by frequent turnover. This is in sharp contrast to sex chromosomes in 2 major vertebrate groups, the mammals and birds, where they are heteromorphic in one sex and are highly conserved.

Sex determination is a major switch in the evolutionary history of angiosperm, resulting 11% monoecious and dioecious species. The genomic sequences of papaya sex chromosomes unveiled the molecular basis of recombination suppression in the sex determination region, and candidate genes for sex determination.

Sex determination is an important developmental event in the life cycle of all sexually reproducing plants. Recent studies of sex determination in many plant species, from ferns to maize, have been fruitful in identifying the diversity of genetic and epigenetic factors that are involved in determining the sex of the flower or individual.

Trends in Genetics, 1988
Abstract Studies on people and mice with sex chromosome abnormalities have established that the gene switching embryonic development into the male rather than the female pathway is located on the short arm of the Y chromosome in both species. How the gene exerts its effects is still a mystery.

Sex Determination in Vertebrates
2018This article provides a short overview of the different sex determination systems of vertebrates and the known genes that initiate sexual development as master regulator in species with genetic sex determination. Besides description of the outstanding variety where the different sex determination systems do not follow any phylogenetic pattern and where

In the few decades following the rediscovery of Mendel’s work, the intense activity in genetics was concerned with collecting many more examples of “Mendelizing” genes, and with analyzing the way in which genes were arranged in, and transmitted with the chromosomes.

Sex determination in Chlamydomonas
Seminars in Cell & Developmental Biology, 2007The sex-determination system of the unicellular green alga, Chlamydomonas reinhardtii, is governed by genes in the mating-type (MT) locus and entails additional genes located in autosomes. Gene expression is initiated by nitrogen starvation, and cells differentiate into plus or minus gametes within 6h.
