Generally a Camelus bactrianus × Camelus dromedarius hybrid is called an F1. It usually has a single large hump, sometimes slightly divided, and is larger than both parents, reaching 230 cm at the shoulder and up to 1000 kg. This type of camel is extremely strong and is useful for hard work such as plowing and carrying loads. It is generally docile and tame. It is fertile.
The F1 can be further hybridized. An F1 female can mate with a male Bactrian camel: the result is a F2 Bactrian. It generally has two humps and is faster than a common Bactrian and stronger than a dromedary. It can walk over snow, ice, and mud and is suitable even for mountain trails; this type can be found mostly in Kazakhstan.
When an F1 female mates with a dromedary, the result is an F2 dromedary, a slightly stronger dromedary and a rare type nowadays.
