White tiger is recessive mutant of Bangal tiger(Orange tiger).
White Tiger is caused by the homozygous occurrence of a recessive allele in genome. Occurrence Reported in Assam,Bangal,Bihar,and espacially in former states of Rewa. Birth Rate Out of 15000 births of orange tiger, there is one birth of white tiger.
Chinchillagene the mutation is recessive to normal colour.
Hetrozygous + Hetrozygous Gives both Orange and White Tigers White + white Gives only WHITE TIGERS.
White + Orange(Homozygous (HomozygousRecessive) Dominant)RESULT; white gene is disappeared. WHY……….?
WHITE + ORANGE(homozygous) (hrtrozygous)RESULT; 50% 50%
Defines strips distance on body. Orange tiger, who inherits two copies of this gene becomes GOLDEN TABBY. White tiger becomes stripless.
White Tiger has an enzyme in their fur which react to temperature. White tiger produced a mutated form of tyrosinase, an enzyme cause production of Melanin, which only function at very low temperature i.e below 37C* or 99F*. That’s why White Tigers are darker at theirs legs,mouth and ear etc. This phenomena is called Acromelanism.
Instress or confusion, White tiger cross their eyes(Squint or partly closed). This disease is known as STRABISMUS. Due to abnormality in optic chiasm. Neurons from RATINA to BRAIN to OPTIC CHIASM, some cross and don’t cross, so the image is projected to wrong HEMISPHERE of BRAIN.
Club foot(short tendons of forelegs) Kidney problems Crooked backbone Twisted neck React strangely to anesthesia(The best drug for immobilizing a tiger is CI 744.) MOTALITY RATE; 80%.
