This study attempts to propose the possibility of the sex reversal in Sinonovacula constricta and Gomphina veneriformis by confirming the changes in the sex ratio with the shell length in the same population level. For analysis of sex ratio, 100 individuals of S. constricta (SL 26.5-95.0 mm) and 2385 individuals of G. veneriformis (SL 15.1-60.1 mm) were used. Sex was analyzed histologically. Both species displayed the tendency of increase in the female proportion with increase in shell length. In this study, changes in the sex ratio in accordance with the growth of S. constricta and G. veneriformis are determined to be indirect evidence that signifies their sex reversal.
本研究试图通过在相同种群水平上确认性别比例随壳长的变化，提出缢蛏和扁玉螺性别逆转的可能性。为了分析性别比例，使用了100只缢蛏个体（壳长26.5 - 95.0毫米）和2385只扁玉螺个体（壳长15.1 - 60.1毫米）。通过组织学方法分析性别。两种贝类均表现出随着壳长增加雌性比例上升的趋势。在本研究中，缢蛏和扁玉螺性别比例随生长的变化被确定为表明其性别逆转的间接证据。
