Approximately what percentage of genes do zebrafish share with humans, facilitating human health studies?
Answer
Approximately 70%
The significant utility of the zebrafish as a model organism is strongly underpinned by its genetic homology with humans. Research indicates that zebrafish share approximately 70% of their genes with humans. This high degree of genetic overlap is crucial because it allows researchers studying complex biological processes or human diseases to use the simpler zebrafish system as a proxy. Furthermore, a substantial portion, about 84%, of genes known to be associated with human diseases have a corresponding homolog in the zebrafish genome, solidifying its role in understanding conditions affecting human physiology.
