Humans Do Not Share 50% of DNA with Bananas
“Humans share 50 percent of their DNA with bananas”
Summary
Humans do not share half of their DNA with bananas. Comparative genomics shows only a modest proportion of genes are conserved, and overall DNA similarity is far below 50%. The claim is a widely repeated myth, not a factual statement.

The results are available within the Musa GBrowse 2 on a track called ‘MusaGenomics consortium ESTs’. Similarly, Genoscope aligned 6 888 879 EMBL monocotyledon mRNAs with Blat and Est2Genome (GBrowse Public monocotyledon EST track). cDNA reads (829 587 from DH-Pahang) produced by 454 technology were aligned to the banana sequence assembly with the same procedure and posted to GBrowse Pahang 454 EST read track.
