Genetic models to explain heterosis Traditional genetic analyses of heterosis are based on the quantitative effects of the genes between two opposite inbred lines. Three major classical genetic models have been suggested to explain the hybrid vigor: the dominance hypothesis explains increased vigor to the action at multiple loci of favorable dominant

Genetics Paper Each human in the world is created both separate and unique. Although members of a family may possess common traits‚ each member has their own individuality.

to another. This is called “genetic engineering.” Genetic engineering also refers to the artificial modification of the genetic code of any living organism. Genetic engineering changes the original physical nature of the organism‚ sometimes in ways that would never occur in nature. Genes from one organism are inserted in another organism‚ most often across natural species boundaries. Some of the effects become known‚ but most do not. There are some examples of genetic engineering that have created
