摘要
Y染色体 (除拟常染区外 )在减数分裂中不发生交换重组 ,呈单倍型传递 ,具有父系遗传特征 ,序列的变异由累积的突变所致。由于 Y染色体的这些特点 ,使得对 Y染色体上多态性遗传标记的研究不仅在人类进化学、遗传学等方面意义重大 ,而且在法医学。
Chromosome Y does not recombine with any other at meiosis except that on pseudoautosomal region. Polymorphic markers on the chromosome Y are paternal inheritance and are haploidly inherited. Variance of the sequences comes from accumulated mutation. These properties make them unique and important not only to anthroponomy and genetics but also to forensic science and medicine.
