  1. 1. I found 3 types, Standard trisomy 21, Translocation, and Mosaicism.
    2. Down syndrome can be tested for during pregnancy or after birth. The diagnosis is always based on the extra copy of chromosome 21, but final diagnosis may be made after birth because of distinct features the child may be born with.
    3. False, most people with Down syndrome are in public education and live somewhat normal lives in society.

  2. 1. Trisomy 21 (about 95% of people with down syndrome have this type) and Mosaicism (occurs in about 1-2% of all people with Down Syndrome).
    2. There are two types of tests, screening and diagnostic tests.The most common screening tests are the Triple Screen and the Alpha-Fetoprotein Plus. These tests measure levels of certain substances in the blood. They can also use an ultrasound, which is when they look for physical signs of down syndrome.
    3. False, many people with down syndrome live mostly normal lives.

  3. 1) Two types of down syndrom are Standard Trisomy 21 and Moaicism.
    2)Two ways to diagnose down syndrom are prenatally and at birth. In testing prenatally a doctor would use screening tests or diagnostic tests. Down syndrom is usually identified at birth by identifying certain physical traits.
    3) False, many children with down syndrom attend regular schools, and most likely live normal lives.
