Heritability and Y-chromosome influence in the jack male life history of chinook salmon (Oncorhynchus tshawytscha).

Heredity - 1 Oct 2002

Heath D D, Rankin L, Bryden C A, Heath J W, Shrimpton J M

Abstract excerpt

Jacking in chinook salmon (Oncorhynchus tshawytscha) is an alternative reproductive strategy in which males sexually mature at least 1 year before other members of their year class. We characterize the genetic component of this reproductive strategy using two approaches; hormonal phenotypic sex manipulation, and a half-sib breeding experiment. We 'masculinized' chinook salmon larvae with testosterone, reared them...
