Question:
Does the Y chromosome change in the male line? For example would my great great great grandfather have had an identical Y to mine?



Replies:
There is a low rate of mutation for all DNA...but his Y chromosome would be close if not identical to yours.

The Y chromosome is passed from father to son and can be used to trace lineages. However, DNA does mutate at a fairly constant rate. When scientists trace chromosomes they take this mutation rate into account.
