Final answer:
Mitochondrial DNA (mtDNA) is inherited maternally, lacks recombination, and stays relatively unchanged. Highly decomposed skeletal remains would have mtDNA but lack nuclear DNA due to degradation differences.
Explanation:
Mitochondrial DNA (mtDNA) is a type of genetic material that is passed down maternally and is found in the mitochondria. Unlike nuclear DNA, mtDNA lacks recombination, so it remains relatively unchanged through generations.
In the given options, Highly decomposed skeletal remains would likely have mitochondrial DNA but lack nuclear DNA since nuclear DNA degrades faster than mtDNA, making it absent in older remains.
