Mitochondrial DNA and the Y chromosome do not undergo significant meiotic recombination, which means that the genetic material passed down is relatively unchanged, making them useful for tracing evolutionary lineages. The size of the mitochondrial genome and the Y chromosome is also small, which makes them easier to work with in genetic analyses.
