One possible explanation for why <u><em>maternal age</em></u> is a primary risk factor for autosomal trisomy is that oocytes remain in meiosis I until ovulation, which could take<em> place many years after birth, making them more susceptible to damage.</em>
Explanation:
Increasing age becomes a risk for abnormal children like children with autosomal trisomy because as the age of the female increases, the chances of abnormal division of chromosomes in the egg of the female also increases. After the age of 30, the chance of having a baby with autosomal trisomy increases exponentially. The risk primarily increase because of the abnormalities in meiosis in the women.
