FBXL4 is a nuclear gene that encodes for a protein called F - Box and Leucine - Rich Repeat Protein 4.

Mitochondrial fingerprinting is normally used when the genetic material in a sample is degraded, for while there are only two copies of each nuclear gene in a cell, there are often hundreds of copies of mitochondrial DNA (mtDNA).

Rather than despairing that combinatorial interactions of diets, nuclear genes, and mitochondrial genes make the underlying biology of aging intractably complex, Rand and lead author Chen - Tseh Zhu said studies that explicitly embrace such multifactorial interactions can lead researchers to understand the inherent biological complexity of the aging process: Many genes, many cells, and many environments all contribute to the aging process.

As subpopulations moved into isolated areas, how did they remain isolated over a long enough time for new species - defining traits to arise in nuclear genes and become enriched by natural selection to permit speciation?
