A more likely possibility is that some types of fruits and vegetables may protect against certain cancers. Women with Turner have one X chromosome only. May be some mutation could have made them to produce more copies of DNA at any point of their life time. Two independent teams of researchers investigating why East Asian people have more Neanderthal DNA than Europeans have reached the same conclusion. They don't have important information in them like genes do, so they can be lost without the cells caring much. Chromosomes that carry genes must be copied exactly from parents to offspring, but things occasionally go wrong.
