Expert Solution

Step 1

Down syndrome is an autosomal trisomy where an affected individual may survive until adulthood.

Individuals with Down syndrome often have mental retardation, some impairment of physical growth, and a specific facial appearance.

The risk of having a child with Down syndrome is higher among women age 35 and older.

Hence the chances of Down syndrome increase with an increase in maternal age.
