Ayoung man wants to determine if he is a descendant of henry of navarre and eleanor of aquitaine—two of his favorite historical characters. he sends a cheek swab to a dtc company and is offered a choice: the company can assess either the sequence of the man's y chromosome or his mitochondrial dna. which should he choose?

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.
