There a bunch breed associations of Shorthorns. The Canadian Shorthorn Association, the Alberta Shorthorn Association, the American Shorthorn Association, etc. Check out the following links I posted for you below.
The Shorthorn breed is not derived from any other breeds like Brangus or Santa Gertrudis or Murray Greys are. Shorthorns were probably originally from the wild Celtic Longhorns, but there is no known records of what the English and Scottish Shorthorns are originated from or where they originally came from when introduced to England, though northern England claims to have been their original home for centuries.
British-type beef breeds.
Angus, Hereford and Shorthorn.
The six dairy breeds in the US are the Milking Shorthorn, Brown Swiss, Holstein, Jersey, Guernsey, and Ayrshire.
Shorthorns are infamous for the genetic abormalities Tibial Hemimelia (TH) and Pulmonary Hypoplasia (PHA) which must be tested for in all Shorthorn breeding stock. This is why the Shorthorn breed has not gained as much ground as other breeds like Herefords and Angus cattle have.
Angus, Red Angus, Polled Shorthorn, Polled Hereford, Brangus, Red Brangus, Red Poll, are the breeds that I can think of that are born naturally polled.

Yes. Mature weights depend on the breed. Smaller breeds of cattle such as Dexter and Jersey mature anywhere between 600 and 1000 lbs. Larger breeds such as Charolais and Chianina mature up to 1600 to 1800 lbs. Most British breeds such as Angus, Hereford, Red Angus and Shorthorn mature between 1000 to 1500 lbs.
The Shorthorn was created in 1919.
That really depends on where you're located. In North America for example, the most common cattle breed is Angus, followed by the Holstein. However, the Composite breed (or "breed" rather) is also the most popular in North America, since it is found on most commercial cow-calf operations and in the majority of feedlots.
