为何男女同种基因型不同表现型
Sometimes,the same genotype in men and women may cause different phenotype,and this is called sex-influenced trait.This may be due to the internal hormone environment or the anatomical disimilarity.
an example would be peopel being bald which is a recessive phenotype in women but dominant in men.So,only one "bald" gene would cause a man to be bald,but two "bald" genes are needed for a woman to be bald.

这是基因选择性表达的结果
