Genetic signatures of lipid metabolism evolution in Cetacea since the divergence from terrestrial ancestor.

abstract：:Genetic architecture fundamentally affects the way that traits evolve. However, the mapping of genotype to phenotype includes complex interactions with the environment or even the sex of an organism that can modulate the expressed phenotype. Line-cross analysis is a powerful quantitative genetics method to infer genet...
