Scientists in Zoos have selectively bred white tigers to keep them the same color. This has resulted in excessive inbreeding. White Tigers in Zoos are now more likely to be born with birth defects.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	Harmful
B	Beneficial
C	Neither
D	None of the above

Explanation:

Detailed explanation-1: -s been said the entire captive white tiger population originated from one single white tiger and has been inbred ever since. In order to retain this recessive gene, zoos and breeders must continually inbreed father to daughter, father to granddaughter and so on. This inbreeding can cause many genetic problems.

Detailed explanation-2: -In the 1950s many zoos deliberately and indiscriminately bred white tigers, but more recently, concerns about the desirability of preserving a trait that presumably hinders tigers‘ to survive in the wild, and recognition that inbreeding could lead to genetic defects, have caused most zoos to such practices.

Detailed explanation-3: -A pure white tiger is totally white without any stripe, which is due to the presence of double recessive allele in the genetic code. It happens only in the Bengal tiger subspecies, and only one in 10, 000 births can have it naturally.
