High school biology has conditioned us to have a Mendel's peas view of genetics -- mom is a yellow pea with a recessive gene for green, dad is also a yellow pea with a recessive gene for green, and they have three yellow kids and one green kid. But during meiosis crossover between maternal and paternal copies of the same gene can occur, leading to the unpaired strand in the resulting sex cell not being an exact match to either parent's chromosome.
We get roughly half of each of our parent's AIM's, but not exactly. With each generation and increasing intermingling of individuals with different AIM's, the effect of this uneven partitioning becomes more pronounced. Thus, we get the folks who visit here and claim they are 7% Native or distant cousins with a common Native ancestor that don't share the same number of AIM's.
