Breaking Down Lineage Factors

Leonel was absolutely fascinated by the idea, but he had so much to learn about it.

How were Lineage Factors formed and passed along? Were they just like the DNA of humans? Or was there another method? 

How were Lineage Factors birthed? If they could come from the future, were there complex time laws to take into consideration? Or was it less about the 'future' and more about a much higher Dimension rewriting something it considered to be trivial in a lower Dimension? 

Could Lineage Factors be snatched and taken? What really was the difference between abilities and Lineage Factors other than the fact the latter was hereditary while the former was not? 

The ability steal Force Arts Leonel had run into in the Joan Zone, could they be used on Lineage Factors as well? Was there much of a difference to begin with? But this line of questioning also led back to what could possibly separate a Lineage Factor from an ability.
