Abstract
The comparative lack of sexual dimorphism of apricot and other [sex-linked] genes studied is due to "sex-limitation", i.e., to a compensatory influence of the dosage difference between the sexes in respect to other genes in the X-chromosome. The facts are of particular interest from an evolutionary standpoint.
摘要
所研究的杏色基因和其他[性连锁]基因相对缺乏性二态性，这是由于“性限制”，即X染色体上其他基因在性别间剂量差异的补偿性影响。从进化的角度来看，这些事实特别有趣。
