Question

Read the following passage carefully :
1. The white tiger is an offspring of Bengal tiger, which has the necessary gene for white colouring. It has beautiful black stripes on a white coat. This species of animal has blue eyes and a pink nose.
2. 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 sub¬species, and only one in 10,000 births can have it naturally. White tigers are rarely seen in the wild and only twelve of them have been spotted in India since last one hundred years. Tigers have a life-span of 10-15 years. They are solitary animals, and are fond of hunting at night. Their diet consists of any animal that they can catch, and can eat up to 40 pounds of meat at one time. After such a big meal, they usually remain away for several days from eating again.
3. They are slow runners, but good swimmers. They are poor climbers and cannot climb a tree easily. They live in an area ranging from 10 to 30 square miles depending upon the availability of prey, water and shelter. Habitat loss, poaching and expansion of human population have together contributed to their being endangered. They are widely hunted for their body parts, which are used in traditional Chinese medicines.
4. Genetic inbreeding is another reason for their endangerment. Due to shortage in their number, this species of animal has been subjected to inbreeding. It has resulted in high mortality rates and severe disabilities. About 80 percent of the white tiger cubs are born with serious birth defects related to inbreeding and they soon die off.
5. The critical condition of this animal has attracted the attention of conservationists worldwide. World Wildlife Federation (WWF), defenders of wildlife, and many other wildlife organizations are working with the support of the government for the cause of protecting them from becoming extinct. Once they become extinct, it will not be possible to bring them back to life.
Based upon your reading of the passage, answer the following questions :
(a) How is the pure white tiger different from the white tiger in its physical appearance ?
(b) What is the scientific reason behind the pure white tigers having no stripes ?
(c) A big meal affects the tiger. How ?
(d) What are the essential features of the place where the tigers live ?
(e) What factors have put tiger's species in the category of the endangered animals ?
(f) Why are they widely hunted ?
(g) How has genetic inbreeding affected the tigers ?
(h) Name any two agencies working for the protection of tigers.

Answer 1

(a) The white tiger has beautiful black stripes on a white coat whereas a pure white tiger is totally without any stripe.
 (b) The scientific reason behind the pure white tigers having no stripes is the presence of double recessive allele in their genetic code.
 (c) After a big meal, the tigers usually remain away from eating again for several days.
(d) They live in an area ranging from 10 to 30 square miles depending upon the availability cs of prey, water and shelter.
(e) Habitat loss, poaching and expansion of human population and also genetic inbreeding have put tiger's species in the category of the endangered animals.
 (f) They are widely hunted for their body-parts which are used in traditional Chinese medicines.
 (g) Due to shortage in their number, this species of animal has been subjected to inbreeding resulting in high mortality rate and severe disabilities.
 (h) World Wildlife Federation (WWF) and Defenders of Wildlife.
