Collaboration between researchers at Kyushu University in Japan and Stanford University in the United States has proved the contrary. Collectively, they revealed the genetic underpinnings that account for why ginger coloring is so prevalent in cats. That simultaneous publication, coincidence aside, reflects a significant and exciting discovery. Male cats are way more likely to show this really specific orange color due to the influence of a special gene.
The new study reveals that the gene ARHGAP36 is essential for pigment synthesis in ginger cats. Among their multi-institution research teams’ findings, they realized that this gene is especially expressed in ginger colors. Recently, scientists found something fascinating about ginger cats. They had a specific deletion sequence of DNA code in the ARHGAP36 gene, which determines the production of lighter pigments.
Female cats are a more complicated case. That’s because they actually have two X chromosomes. Both of these chromosomes must be missing the same section of DNA for them to produce paler pigment similar to their male siblings. That genetic difference unlocks a fascinating truth about female cats. They’re more likely to feature mixed coloring, as opposed to the typical males who lean toward the full orange solid coloring.
“These ginger and black patches form because, early in development, one X chromosome in each cell is randomly switched off,” – Prof Hiroyuki Sasaki, a geneticist at Kyushu University.
The study required a deep dive into the DNA of hundreds of orange cats and non-orange cats. This method enabled the researchers to identify exactly which genetic variations produced the signature colorization. These results came as a surprise and a true delight to the scientific community and to the thousands of felines’ friends who funded this groundbreaking study.
Crowdfunding efforts contributed to bringing the study to life, raising an incredible 10.6 million yen (around £55,109). This accomplishment reflects the love and support of kitty lovers from Japan and all over the world.
“As cells divide, this creates areas with different active coat colour genes, resulting in distinct patches.” – Prof Hiroyuki Sasaki.
Long before DNA was discovered, animal breeders understood the role that genetics played in coat color in cats. This is particularly the case with orange tabby cats. Just how this phenomenon occurs had been a mystery until now. The collaborative work between the two research teams has not only clarified existing knowledge but has opened new avenues for exploration.
Most cat owners have heard the idea that a cat’s coat color and pattern can tell you what kind of personality to expect. Scientific evidence to support this theory is proving still elusive.
“Many cat owners swear by the idea that different coat colours and patterns are linked with different personalities,” – Prof Sasaki.
He added, “There’s no scientific evidence for this yet, but it’s an intriguing idea and one I’d love to explore further.”
