The "Eve Gene," often associated with mitochondrial DNA, is inherited solely from the mother and does not play a role in determining traits like skin or eye color. Mitochondrial DNA is crucial for energy production within cells but lacks the genetic instructions for visible characteristics, which are coded in the chromosomal DNA.

Chromosomal genes, on the other hand, come from both parents and are randomly allocated during reproduction. Each parent contributes half of their chromosomes, and the random combination of these genes determines a child's traits. This process ensures genetic diversity and explains why siblings can look different despite sharing the same parents. The Eve Gene highlights maternal lineage but is unrelated to the inheritance of visible traits or the genetic lottery of chromosomal allocation.
