Scientists use fractions and percentages to give numeric backing to their conclusions and informing their audience about the proportional weighting in the results. For instance:
Do dogs share ¾ of human genes?
Analysis in 2003 in the US by a gene mapping team including Dr Craig Venter showed that for 75% of known human genes - lengths of DNA that provide the building instructions for proteins - there was an equivalent dog gene. A total of 18,473 of the known 24,567 human genes had a canine version. The researchers used Craig’s male poodle as their DNA source.
18,473 = 0.7519 = about 75% of 1 = about ¾
24,567
