1. Trisomy 21-most common 95% of people with Down Syndrome have it, it is when the person only gets 1 copy of chromosome 21 in their cells
2. Translocation Down Syndrome- approximately 4% of people with Down Syndrome have it, it is where the person gets 2 copies of chromosome 21 in their cells
3. Mosaicism (Mosaic) Down Syndrome- the last 1% of people with Down Syndrome have this, in this type the body cell’s have 3 copies of chromosome 21 in their cells, where the areas typically have 2

During anaphase ll the sister chromatids don’t separate in meiosis ll. When this gamete with 24 chromosomes fuses with another gamete with 23 chromosomes it makes a zygote with 47 chromosomes, resulting in the offspring to have down syndrome.

Down Syndrome Cell division is of vital importance to our body. The division of cells occurs in two ways, mitosis and meiosis. Cell division occurs from chromosomes, which are the holders of genes. Many errors can occur during cell division, within the chromosomes. In meiosis, the pairs of chromosomes are supposed to split up and go to different spots in the dividing cell, this is referred to as disjunction. But sometimes one pair doesn’t divide, and the whole pair goes to one spot. This means…
