Diversity of sex determination in fish - everything is possible?
Abstract: Fish show the greatest plasticity of sex determination (SD) mechanisms amongst vertebrates ranging from environmental SD to highly complex forms of genetic SD. In the case of genetic SD this is linked to a similarly high variability of sex chromosome differentiation. To explain this variety in an evolutionary, ecological and developmental biological context major paradigms and hypothesis have been phrased. A comparative view on SD in several species across the fish tree of life will be presented as a baseline for discussions on hypotheses that explain the evolution of sex chromosomes and how new SD mechanisms arise again and again.

IGB Colloquia open up!
IGB strives to facilitate and accelerate the exchange of knowledge and ideas within and also outside of IGB. One element contributing to inter- and transdisciplinary exchange, and more (scientific) cooperation and innovation, is to open up IGB Colloquia to an interested external audience from science (other research institutes, universities, laboratories) as well as practice (i.e. conservationists, freshwater/land-use managers, authorities, associations). If you would like to join this IGB Colloquium as a guest, we ask you to register until the morning of the colloquium 10 o'clock the latest. After we have checked your registration, you will receive the participation link.
