SDS
Role and evolution of a possible major sex determinant in Salmonids
Context
In genetics, “major sex determinant” is the gene that triggers the process of differentiation of the gonads of the embryo and directs them towards the formation of ovaries or testicles. In salmonids, the sex determination system is known to be type XX for females and XY for males, as in mammals. The SDY gene is specifically expressed in embryonic male gonads in rainbow and brown trout. The SDY gene could then be the major sex determinant in these two species and possibly other salmonids.
Objective
Studying the role and the evolution of a possible major sex determinant in Salmonids.
About the <strong>project </strong>
The main objectives of the SDS project are to characterize the function of the SDY gene in rainbow trout, verifying whether it is indeed a major sex determinant. Then, it aims at studying its molecular and functional evolution within salmonids.
This project will also have important practical benefits by providing a tool for genetic sexing in aquaculture, ecotoxicology and ecology.
