Unlike the 16S rRNA gene phylogenetics used to identify relatedness in Bacteria,the 18S rRNA gene is by itself unreliable for phylogeny of members in Eukarya.

Question

Quizplus · Accepted Answer

The 18S rRNA gene is often not enough to accurately determine evolutionary relationships within Eukaryotes due to its high conservation and slow rate of evolution. In addition, other genes and molecular markers are often needed to complement phylogenetic analyses in this domain.
