Why hasn’t science introduced Angora goat genes into sheep to produce better wool?

There’s not much point.

Angora goat fibre, aka mohair, has its own qualities. It’s primarily used for making suits as it’s quite hardy, but it’s not usually suitable for next-to-skin garments.

Meanwhile, in the sheep world, there’s a humongous range of qualities. Merino and Blue-faced Leicester for under-clothing and babywear, Wensleydale for silk-like, drapey clothing, Icelandic for sturdy cold-weather outerwear, Shetland for lightweight but warm socks and sweaters, Scottish Blackfaced for carpetting, through to mixed-breed meat-sheep’s scraggly fleece that’s only good for house insulation or composting.

Goat genes would add nothing that isn’t already available in one or other sheep breed.
