《生物学教学》1998年第3期上刊登的《一个基因型为FfGg的精原细胞只能形成二种类型的精子吗》一文，我觉得该文的分析有些地方欠缺。《生物学教学》1997年第7期上刊登的北京市1996年普通高中毕业会考生物学试卷中的原题是：已知某糖原细胞的基因型为FfGg，由它形成的四个精子 In “Biology Teaching”, published in the third issue of 1998, “A spermatogonia with a genotype of FfGg can only form two types of sperm”, I think that the analysis of this article is lacking in some places. The original title of the 1996 Beijing Biology Examination Book for Senior High School Students, published in the 7th issue of Biology Teaching, is: It is known that the genotype of a glycogen cell is FfGg, and four spermatozoa are formed by it.
