摘要: One pair of recessive major gene and several modifiers dominated the major gene of Gaoyou duck's double yolk egg. The fitness of double yolk egg trait was analyzed by population genetics one the basis of special environment and natural geography. The results showed that the double yolk egg trait fitness was 8.23 under artificial selection during the year 2000-2002. The equilibrium of high intensive artificial selection and natural selection resulted in the trait of Gaoyou duck's double yolk egg.
