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

但是多数灵长包有着三感光素，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.

研究方法主要是藉层分析法，如层分析法，薄层层分 析法及高压液相层析法等方法以达分离、分析和定量素的目的。
