FMC clustering is used for gene expression data, a combination of kernel regression and projection pursuit regression introduced into the design of predictors, and coefficient of determination used as a criterion in selecting the target gene s parent sets.

The correlation coefficients between the traits were calculated,and then multiple regression analysis and path analysis were conducted by taking the adductor weight as a dependent variable and other six economic traits as independent variables;the corresponding path coefficients and determination coefficients were also calculated.

The path analysis procedure was utilized to investigate the total effect of 5 morphological traits on the body weight of Scapharca subcrenata and the total decision coefficient was used as a criterion for determination of relative impor.
