. Which part of sheep has fibres that are used to make wool
The hairy skin of the sheep has two types of fibres that form its fleece:
(i) the coarse beard hair
(ii) the fine soft under-hair close to the skin.
The fine hair provides the fibres for making wool.
Some breeds of sheep possess only fine under-hair.
Final Answer: Hence the coarse beard hair and the fine soft under-hair close to the skin are used to make wool.
