Genetic Aanalysis of Size in an Anadromous Population of Pink Salmon
Variation of size, particularly among males, has a significant genetic basis in pink salmon (Oncorhynchus gorbuscha) in Auke Creek, southeast Alaska. Heritability (h 2 ), based on variance components of 118 full sib − 59 paternal half sib families of mature fish tagged as fry with coded micro wires,...

Variation of size, particularly among males, has a significant genetic basis in pink salmon (Oncorhynchus gorbuscha) in Auke Creek, southeast Alaska. Heritability (h 2 ), based on variance components of 118 full sib − 59 paternal half sib families of mature fish tagged as fry with coded micro wires, are higher in males (h 2 length: 0.8 ± 0.3 (mean ± SE); h 2 weight: 0.6 ± 0.2, based on sire effect) than in females (h 2 length: 0.3 ± 0.2; h 2 weight: 0.4 ± 0.2). Realized heritability probably would be smaller because of environment variability between brood years in factors affecting size and growth. Estimates based on regression of offspring means on fathers' values are smaller (h 2 length: 0.4 ± 0.1 in males; 0.2 ± 0.1 in females; h 2 weight: 0.0 in males and 0.1 ± 0.1 in females). Estimates of genetic, environmental, and phenotypic correlations of length and weight are all >0.7 (SEs <0.1). Estimates of genetic correlation between length and day of migration from the sea are near 0.4 ± 0.2; estimates of environmental and phenotypic correlations between these traits are smaller (<0.2, SEs <0.1). |
