A nurse comments that the only aneuploid conditions he has seen in his practice are Patau syndrome, Edwards syndrome, and Down syndrome. What rationale would the genetics specialist suggest?
◦ The diagnosis of aneuploidy is made early in the pregnancy, so women whose fetuses demonstrate other conditions are referred to high-risk providers.
◦ These are all monosomic conditions, which have a higher survival rate to delivery.
◦ The chromosomes affected are small.
◦ Spontaneous abortions are rare among fetuses with these conditions.
