Question

Which of the following is characterised by the fine soft under hair?
A. Yak
B. Goat
C. Sheep
D. All of the above

Answer 1

Animal fibres are natural fibres made up primarily of proteins. Silk, hair/fur (including wool), and feathers are examples. Wool from domestic sheep and silk are the most often utilised animal fibres in the manufacturing industry as well as by hand spinners. Alpaca fibre and Angora goat mohair are also quite popular. Unusual fibres like rabbit Angora wool and dog Chiengora are also available, but they are rarely used in mass production.
Animal fibres aren't all the same, and even within a species, the fibre isn't always consistent. Merino wool is exceptionally soft and thin, but Cotswold wool is coarser, despite the fact that both Merino and Cotswold sheep are breeds of sheep.

Complete answer:
Option A: Some animals are chosen specifically for their ability to reproduce and give birth to offspring. This procedure is carried out in order to create animals with unique characteristics. Sheep are selectively bred to produce sheep with only fine, silky hair.
So, option A is not correct.
Option B: Some sheep breeds have only fine under-hair. Their parents have been chosen specifically to give birth to sheep with exclusively soft underhair. Selective breeding is the practise of selecting parents for unique characteristics in their offspring, such as soft underhair in sheep.
So, option B is not correct.
Option C: Sheep have two different types of hair: fine underhair and coarse hair. Sheep have coarse hair on their exterior coats, which are long and rough. Sheep's underhair is fine and silky, and it grows closer to the skin.
So, option C is correct.
Option D: Some animals are chosen for their ability to reproduce and give birth to children. This process is used to develop creatures with distinctive features. Sheep that have just fine, silky hair have been selectively bred.
So, option D is not correct.

Therefore, Option C is the correct answer.

Note:
Sheep, yak, Angora goat, camel, and other animals provide wool. These animals have a thick outer coat of fur or fleece on their bodies that aids in body temperature regulation. Wool is mostly obtained from sheep in India. Angora wool may be found in the majority of Jammu and Kashmir's regions. Yak wool is widely available in Tibet and Ladakh.
Sheep have two different types of hair: fine underhair and coarse hair. Sheep have coarse hair on their exterior coats, which are long and rough. Sheep's underhair is fine and silky, and it grows closer to the skin. Fleece refers to the fine, silky underhair. This fleece is the primary source of fibres for the sheep.
