Being slightly more specific; any persons DNA is exactly 50% of the mothers and the fathers, but the distribution is random. Two children to the same parents will have a different selection of DNA from both parents.
Think of it this way, both parents have 100% of their DNA (made up of a mix of their parents); which when joined to make a child, the 200% of DNA comes together, is thrown in a blender and one half (100%) is thrown away. The 100% remainder becomes the child.
