30.14 MOLECULAR GENETICS AND FISHERY SCIENCE

Parker, Nick C. (U.S. Fish and Wildlife Service, Texas Cooperative Fish and Wildlife Research Unit, Texas Tech University, Lubbock, TX 79409-2125)

The evaluation of modem molecular genetic techniques and associated technical terms and jargon such as DNA probes, plasmids, recombinant DNA, transgenic, ploidy manipulation, and sex reversal, may seem foreign and confusing to many biologists and even more so to the layperson. This brief overview of the major elements of molecular genetics, explained in lay terms, is an attempt to increase understanding and communications between layperson and the scientific community. Special applications of molecular genetic techniques in the field of fishery science include production of monosex populations, polyploid fish, and use of DNA probes to identify or classify unknown tissue samples and biopsies by species, sex, geographic origin, or specific genotypic traits.
