Now that we know (based on the previews for the next episode of 'Heroes') that Nikki Sanders' husband DL Hawkins has powers as well, it seems clear that their son Micah will prove to be genetically gifted as well.
We already know he's a computer whiz, incredibly smart; before the end of the season, we may learn what else Micah is capable of doing.......
This is just one of my Theories of Relateeveety, but it could be that Nikki chose the name "Micah" for her son from her own family tree. She may have selected that name from the many in her family's background just because she liked the sound of it.
So it could be that far back in her genealogy, Nikki is descended from Micah Torrance, who was the sheriff of North Fork, New Mexico, back in the 1880s.
Micah Torrance might have other branches on his particular family tree; one of which could possibly lead to Dr. Mark Piper, who served on the starship Enterprise before retiring and being replaced by Dr. Leonard McCoy.
