Genotype by nutrition interactions for immunoresponsiveness and disease resistance in chickens
… and disease resistance in several genetic stocks maintained under different nutritional regimens. Genetic stocks included (1) a commercial layer line, (2) commercial broiler lines, (3) a White Rock line selected for high juvenile body weight, (4) a White Leghorn line selected for …

Bilateral Asymmetry in Chickens of Different Genetic backgrounds
… to study developmental stability of various genetic stocks at different stages in the life cycle. The primary measures of stability were type and degree of asymmetry of bilateral traits and heterosis. Higher relative asymmetry (RA), which was defined as (|L-R| / [(L+R)/2]) x 100, was observed …

Genetic evaluation of walleye (Stizostedion vitreum vitreum) stock structure and recruitment in Claytor Lake, Virginia
… of primarily Kansas origin. A biochemical genetic approach was used to evaluate the present stock structure of Claytor Lake walleyes. Electrophoretic phenotypes for skeletal muscle malate dehydrogenase (MDH) and parvalbumin were identified (using starch and polyacrylamide gel …

Genetic Characterization of Intermixed Walleye Stocks in Claytor Lake and the Upper New River, Virginia
Historically, the New River may have contained a genetically unique, river-spawning population of walleye (Stizostedion vitreum). Additionally, a number of genetically different walleye stocks have been stocked in Claytor Lake, Virginia. The increasing importance of the walleye fishery led to …
