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.

Answer:
Land can become polluted by household garbage and by industrial waste. In 2014, Americans produced about 258 million tons of solid waste, according to the U.S. Environmental Protection Agency. A little over half of the waste — 136 million tons— was gathered in landfills. Only about 34% was recycled or composted. 
Hope this helps and I hope its correct.
