Delomas and Dabrowski (2016) detail a new method for performing haploid gynogenetic screens in zebrafish in a recently published article in the scientific journal, Biology Letters. The described method uses UV-irradiated common carp (koi) sperm to induce zebrafish embryonic development. This method will allow the biomedical industry and other research laboratories to rapidly screen zebrafish for unique genetic mutations. Finding new mutations helps us learn about human disease and developmental biology.
