نمر أبيض

من أجل استخدامات أخرى، انظر نمر أبيض (توضيح).

النمر الأبيض white tiger (Panthera tigris) هو نمر ذو حالة جينية تزيل تقريباً كل الصبغة في فروه الذي يكون برتقالي اللون في النمر العادي إلا أن الشرَط السوداء تبقى كما هي. ويحدث هذا عندما يرث النمر نسختين من الجين المتنحي للتلوين الشاحب: أنف وردية, مخالب وردية, جلد رمادي-مرقط, وعينان لنهما أزرق ثلجي وفراء أبيض إلى لون القشدةمع شـُرَط سوداء أو رمادية أو بلون الشوكولاتة. Mr. H.E. Scott of the Indian police gave this description of a captive white tiger's eyes-"The colourings of the eyes are very distinct. There is no well defined division between the yellow of the comex and the blue of the iris. The eyes in some lights are practically colourless merely showing the black pupil on a light yellow background."[1] (Another genetic condition also makes the stripes of the tiger very pale; white tigers of this type are called snow-white.)
