摘要

虽然样本很小,但代表了1972年至1974年在约翰内斯堡国廷小学和中学就读的儿童总数。在男性和女性样本中,非味觉基因的频率为0.167。红绿色盲的基因存在于约翰内斯堡的中国人中,但频率很低,只有0.012个。初潮的平均年龄为12,8+/-1,23岁,比许多高加索人的平均年龄记录要年轻。有人认为,这种平均年龄的差异可能反映了不同的遗传因素,而不是不同的社会经济因素。

Studies on the ability to taste phenylthiocarbamide; red-green colour blindness and the age at menarche in Johannesburg Chinese school children.

The sample, although small, represents the total number of children attending the Johannesburg Chinese Kuo Ting Primary and High School in 1972 to 1974. The frequency of the non-taster gene was found to be 0,167 in the combined male and female sample. The gene for red-green colour blindness is present in the Johannesburg Chinese population but at low frequnecy, 0,012. The mean age at menarche was found to be 12,8+/-1,23 years and is younger than the mean ages recorded for a number of Caucasoid populations. It is suggested that this difference in mean age reflects possibly varying genetic rather than varying socio-economic factors.
