Multiple paternity and variance in male fertilization success within Atlantic salmon Salmo salar redds in a naturally spawning population
The incidence and magnitude of multiple paternity were estimated for a natural, unmanipulated spawning population of Atlantic salmon Salmo salar . Egg nests were surveyed in the autumn and sub‐samples were excavated the following spring. Parentage data derived from microsatellite DNA revealed an une...
