Growth traits of Zhikong scallops in a population with respect to genotypes at SNP c. 1815C>T in the <i>Tgfbr1</i> gene.

N, number of scallops; GF, genotype frequency (%); SL, shell length (mm); SH, shell height (mm); BW, body weight (g); STW, soft tissue weight (g); SMW, striated muscle weight (g). The growth traits are given as the mean ± standard deviation. The values with different superscripts within each column are significantly different (P<0.05). Significant difference was detected in SMW values between genotype CC and TT (p = 0.037), and between CT and TT (P = 0.031).
