In brief: Pregnancy mutations

Conception is a function of two sets of chromosomes, 22 + X from an egg and 22 + X or Y from a sperm.
The resultant combination goes through a "re-mixing"_ process that requires pairing the chromosomes with subsequent "detachment" If the detachment process is not a complete "pair", then gene mutations occur especially in women older than age 37.
