Association between Growth and Pan I* Genotype within Atlantic Cod Full‐Sibling Families
Abstract Studies of the pantophysin ( Pan I *) locus in Atlantic cod Gadus morhua and other marine gadoids indicate that the locus is under positive selection; in Atlantic cod, genotypic variation at this locus has been linked to differences in growth. Here, we present preliminary data comparing the...
