suicidal Male mitocondria?

    another of life's little curiosities:

    aka paternal mitochondria elimination(PME):
    Sperm has its own mitochondria
    It seems that
    should it be quick and lucky enough to find and enter an egg
    via cps6 (which it also carries) the paternal(male) mitochondria will be eliminated
    should the paternal cps6 be defective, missing, or insufficient to eliminate the male mitochondria(usually before the 64 cell stage), the female(maternal) provided cps6 will attempt the job of paternal mitochondria elimination
    should that fail
    the woman's body will just reject the egg and try again next month

    with me so far?
    (here's the question)
    why does a woman's body refuse to carry a zygote with paternal mitochondria?
    would we have evolved differently if that was different?
