The simplest way to determine this is to take the mtDNA 16S human nucleotide sequence and then go to the NCBI website and blast that sequence against the human reference.  To find that website simply google "NCBI BLAST".  The human 16S sequence can also be obtained from NCBI.  That will give you a list of all sites in the reference sequence that match the 16S gene, and there will be several.

Repeat the same process with the mtDNA 16S chicken nucleotide sequence and the chicken reference genome.
