Juana Summers: 我认为橙色猫是最棒的,应该从讨论橙色猫开始。我的橙色虎斑猫Zuko也这么认为。 Regina Barber: 我的橙色猫Benny也同意橙色猫是最棒的。大约80%的橙色猫是雄性,这与橙色基因位于X染色体有关。科学家们已经找到了导致橙色猫的突变基因,位于X染色体上,导致附近的基因在色素细胞中表达。我们与爱猫人士和社区科学家合作,收集了许多橙色猫的DNA样本。 Emily Kwong: 橙色猫的颜色是性连锁的,决定姜黄色突变基因位于X染色体上。其他橙色动物的橙色与性染色体无关,橙色猫非常特别,所有橙色猫都有相同的突变。两个科研团队独立发现了这个突变,研究结果发表在《当代生物学》期刊上。

Chapters
Approximately 80% of orange cats are male. This is because the orange color gene is located on the X chromosome. Two research teams independently discovered the specific mutation responsible for this coloration.
  • 80% of orange cats are male
  • Orange color is a sex-linked trait, found on the X chromosome
  • A single deletion on the X chromosome causes a nearby gene to be expressed in pigment cells
  • The same mutation is found in all orange cats

Shownotes Transcript

Approximately 80% of orange cats are males, including the four orange cats owned by the *Short Wave *team. Scientists have long suspected that orange color was a sex-linked trait — hiding somewhere on the X chromosome. Now, scientists at Stanford University and Kyushu University in Japan have characterized the mutation responsible for orange cat coloration. Both groups published their results in the journal Cell Biology) this week. *Have a question about the animals all around us?
