大多数橘猫是雄性的,这与遗传学有关!负责橘色毛发的基因位于X染色体上,属于性连锁基因。具体来说:
- 雌性猫有两条X染色体 (XX),而雄性猫有一条X和一条Y染色体 (XY)。
- 要表现出橘色毛发,猫必须在X染色体上携带橘色基因。
对于雌性猫来说,它们需要在每条X染色体上都携带橘色基因,才会呈现橘色毛发。然而,雄性猫只需在它们的唯一一条X染色体上携带一个橘色基因就能表现出这种特征。
这就是为什么橘猫约有80%是雄性,只有约20%是雌性——雄性更容易表现出橘色,因为它们只需要一个橘色基因,而雌性则需要两个。
Saya setuju dengan anda. Saya dulu memiliki kucing orange dan dia jantan, tapi dia sudah mati..
