祖源分析和y染色体的关系

最近一直在根据祖源分析来推测祖先的来源和移动轨迹。可我一直想不通祖源分析结果和y染色体的关系。既然y染色体一直是父亲传给儿子，而男男不可能生孩子。那y染色体的变化是怎么来的呢？

1、Y染平均每100年左右就能有一个突变
2、Y染色体和你的祖源没关系（甚至几乎对你的身体没任何作用，以暂时研究来看），祖源是常染色体
3、祖源是有爷爷奶奶外公外婆共同遗传给你的

染色体每次复制的过程中都可能会出现变异，一般有害的变异会导致精子失活。极少数变异是无害的，或者是有利的。如果恰好这些变异精子和健康的卵子结合，就会诞生新的类型的y个体。也就是父子的y会有些许的差异。
y会影响祖源但不影响常染色体祖源，因为y是性染色体不是常染色体。

Y染色体和你的祖源没关系，楼上真能说，哈哈。Y能决定你是男是女，还说明影响不大。😌
