Refer to the gene tree shown. Ribosomal RNA genes are present in the nuclear genomes of eukaryotes.There are also rRNA genes in the genomes of mitochondria and chloroplasts.Therefore photosynthetic eukaryotes have three different sets of rRNA genes, which encode the structural RNA of three separate sets of ribosomes.Translation of each genome takes place on its own set of ribosomes.The gene tree shows the evolutionary relationships among rRNA gene sequences isolated from the nuclear genomes of humans, yeast, and corn; from an archaeal species (Halobacterium), a proteobacterium (E.coli), and a cyanobacterium (Chlorobium); and from the mitochondrial and chloroplast genomes of corn.

If you were to sequence the rRNA genes from human and yeast mitochondrial genomes, where would you expect these two sequences to fit on the gene tree?
