祖源分析和y染色體的關系

最近一直在根據祖源分析來推測祖先的來源和移動軌跡。可我一直想不通祖源分析結果和y染色體的關系。既然y染色體一直是父親傳給兒子，而男男不可能生孩子。那y染色體的變化是怎么來的呢？

1、Y染平均每100年左右就能有一個突變
2、Y染色體和你的祖源沒關系（甚至幾乎對你的身體沒任何作用，以暫時研究來看），祖源是常染色體
3、祖源是有爺爺奶奶外公外婆共同遺傳給你的

染色體每次復制的過程中都可能會出現變異，一般有害的變異會導致精子失活。極少數變異是無害的，或者是有利的。如果恰好這些變異精子和健康的卵子結合，就會誕生新的類型的y個體。也就是父子的y會有些許的差異。
y會影響祖源但不影響常染色體祖源，因為y是性染色體不是常染色體。
