Answer:
He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.
Explanation:
- Mitochondrial DNA haplotypes are specific regions of mitochondrial DNA that cluster with other mitochondrial sequences to show the phylogenetic origins of maternal lineages.
- Mitochondrial DNA haplotypes are associated with a range of phenotypes and disease.
- Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
- Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
