Recent advances in understanding yeast genetics of sex determination.

Sex determination is among the most fascinating areas of study in modern genetics and encompasses many topics, such as developmental mechanisms, behaviour, sex chromosome biology, population evolution and diversity. Yeasts from the subphylum Saccharomycotina are of great importance to humans, not only as pathogens but for numerous essential ecosystem services and serve as model to study evolution in action. The recent advent of inexpensive sequence information and other new tools has led to notable advances in our understanding of reproductive mechanisms over a broad range of species, revealing that genetic sex determination occurs in different ways with a myriad of outcomes in yeast.
