在香港金山郊野公园，我们发现了全身都是白色毛发的猕猴。通过形态学对比，我们发现，与普通猕猴（Macaca mulatta）相比，白猴子的毛发颜色要浅很多、呈白色，毛尖带淡黄色，皮肤、四肢、指甲颜色比普通猕猴要浅很多，瞳孔颜色比普通猕猴稍浅，眼白部分呈红色。由此初步确认这是得了白化病的普通猕猴。

对白化猕猴观察，我们发现它与猴群其它猕猴有相互打闹、相互梳毛的现象，这与资料中提到的白化猕猴会被猴群排挤有所不同。

通过发病率调查，我们得出香港白化猕猴的发病率在1/116～1/600，远远高于以往资料提及的野生动物中白化病的比率（1/20000～1/1000000）。我们猜想，很可能是在香港政府进行猕猴绝育计划时，一些携带正常基因的猕猴被绝育，而一些携带白化基因的猕猴没有被绝育。在后代繁殖中，白化基因就被人为的放大了。

In Hong Kong Kam Shan Country Park, we noticed some white-furred macaques. Through morphological comparison with ordinary Macaque mulatta, we found that the white monkey' fur was much lighter, being white with light yellow fur tips. The white monkey skin, nails, limbs was also much lighter, the pupil color was slightly lighter, the sclera was red. So we tentatively determine these white monkeys are albino Macaca mulatta. 

Observing the albino monkeys, we found they can get along well with other monkeys in the monkey troops by playing and grooming, which is very different from the description that albino monkey will be excluded by their troops. 

Through morbidity statistics, we concluded that the rate of albino monkeys in Hong Kong is 1/116-1/600, which is much higher than the rate of albinism in wild animals mentioned in previous statistics (1/20000-1/1000000). We hypothesis that the reason of the abnormal rate is because the monkey carrying ordinary gene are sterilized, and monkeys carrying albino gene are no sterilized, in the contraceptive programme conducted by Hong Kong government.
