國際時事跟讀VIP Ep. L027: Feline Genetics Revealed: Secrets Behind Cat Behavior and Coat Colors

Highlights 主題摘要

• Scientists discover that genes significantly influence cats' vocal behaviors and social interaction patterns with humans.
• Orange cats possess unique genetic mutations explaining why approximately eighty percent of ginger cats are male.
• Research reveals complex relationships between cat genetics, personality traits, and domestication over thousands of years.

Cat owners have long observed fascinating differences in their pets' personalities and behaviors. Some cats are vocal attention-seekers who greet visitors enthusiastically, while others prefer quiet observation from a distance. These behavioral variations have puzzled researchers for decades, leading scientists to investigate whether genetics might explain why some cats become chatty companions while others remain reserved. Recent groundbreaking studies from Japan and the United States have begun unraveling genetic mysteries behind feline behavior and appearance. Researchers are discovering that house cats carry genetic secrets influencing vocal habits and coat colors.

養貓的人都知道，每隻貓的個性和行為差很大。有些貓很愛叫、很愛撒嬌討關注，客人來了也會跑去打招呼；有些貓比較安靜，喜歡躲在遠遠的地方觀察。這些行為差異讓研究學者困惑了好幾十年，他們想知道基因是不是能解釋為什麼有些貓很愛聊天，有些貓比較內向。最近日本和美國的重大研究開始揭開貓咪行為和外表背後的基因秘密。研究人員發現家貓身上帶有影響叫聲習慣和毛色的基因密碼。

Japanese researchers at Kyoto University found that genes significantly influence how vocal cats are with human companions. By studying hundreds of cats and analyzing genetic markers, scientists discovered that certain gene variants make cats more likely to purr frequently and meow for attention. Male cats with specific genetic variations scored higher for directed vocalizations like meowing to be fed or let outside. Female cats with the same genetic makeup showed different traits, often displaying more aggressive behaviors toward strangers. These findings suggest genetics play crucial roles in determining whether cats develop chatty personalities or prefer quieter lifestyles.

京都大學的日本研究團隊發現，基因會大大影響貓咪跟人類互動時的叫聲表現。他們研究了幾百隻貓咪並分析基因標記後發現，某些基因變異會讓貓咪更容易常常呼嚕叫，也更愛叫來引起注意。有特定基因變異的公貓在特定叫聲方面表現更明顯，像是要吃飯或要出去時會叫。有相同基因的母貓則表現出不同特質，通常對陌生人比較有敵意。這些發現顯示基因在決定貓咪會不會發展成愛聊天的個性，或是比較喜歡安靜生活方面扮演重要角色。

International research teams have finally solved the decades-old mystery of orange cat genetics. Scientists discovered that ginger cats possess a unique genetic mutation on their X chromosome that creates their distinctive coloration. This mutation explains why approximately eighty percent of orange cats are male, since males only need one copy of the gene to display the orange trait. Female cats require the mutation on both X chromosomes to become fully orange, making them much rarer. The genetic variant responsible for orange coloring appears completely unique to domestic cats and hasn't been found in other animal species worldwide.

國際研究團隊終於解開了橘貓基因這個幾十年來的謎題。科學家發現橘貓的X染色體上有獨特的基因突變，造就了牠們特殊的毛色。這個突變解釋了為什麼大概八成的橘貓都是公的，因為公貓只要有一個基因就能表現出橘色。母貓需要兩個X染色體都有突變才會變成全橘色，所以比較少見。造成橘色毛色的基因變異似乎是家貓獨有的，在全世界其他動物身上都沒發現過。

These discoveries open exciting new research possibilities about connections between genetics, behavior, and appearance in cats. Scientists are particularly interested in exploring whether genetic factors that create orange coloring might also influence personality traits, potentially explaining why many cat owners believe orange cats have distinct temperaments. The research raises broader questions about how domestication has shaped feline genetics over thousands of years. Future studies will investigate whether understanding these genetic mechanisms could help explain other mysterious aspects of cat behavior and health, potentially improving how we care for feline companions.

這些發現為貓咪基因、行為和外表之間的關聯性開啟了很多新的研究方向。科學家特別想知道造成橘色毛色的基因是不是也會影響個性，這或許能解釋為什麼很多貓奴都覺得橘貓有特別的脾氣。這項研究也提出更大的問題：幾千年來的馴化是怎麼塑造貓咪基因的。未來的研究會探討了解這些基因機制是否能幫忙解釋貓咪行為和健康的其他神秘面向，可能讓我們更懂得怎麼照顧貓咪夥伴。
