But many primates, including humans, hae a third photopigment, encoded by a second gene on the X chromosome.

但是多数灵长类类有着三感光素，通过在X染体中的第二基因编码。

The results showed that the variation of the color display were not significantly corelated with the composition of the photopigments of their zooxanthella.

研究方法主要是藉分析法，如滤分析法，薄分 析法及高压液相析法等方法以达分离、分析和定量素的目的。
