Found factual errors from my previous post, after doing last round of research. Should've done it before submitting...

The ova are not in haploid state for the lifetime of the female, but in diploid state, arrested at prophase of meiosis I. Couldn't find out how much cellular activity they have at this stage, but anyway, there is thus still one DNA replication at only a short period before possible fertilization. This renders much of my above argumentation mostly null. Indeed could be the DNA of ova and spermatozoa isn't expressed at all at the haploid cell. This would leave the pre-birth selection pressure only to spontaneous zygote abortions (which have other explanations than mere point mutations to them as well).
