Autosomal
Amounts of DNA inherited: approximately 50% from each parent, 25% from each grandparent, 12.5% from each great-grandparent, 6.25% from each 2x great-grandparent, and so on.

Recombination: Genetic recombination randomly “chops” up DNA in each successive generation as a child is being conceived.  For example: In creating the child’s chromosome 1, segments are taken from the father’s chromosome 1 and alternated with segments from the mother’s chromosome 1.  Usually up to a total of 3 segments.
