Male mating strategy and the introgression of a growth hormone transgene
Abstract Escaped transgenic organisms (GMO’s) may threaten the populations of their wild relatives if able to hybridize with each other. The introgression of a growth enhancement transgene into a wild Atlantic salmon population may be affected by the transgene’s effects not only on fitness parameter...
