A #crossbreed is an organism with #purebred parents of two different breeds, varieties, or populations. Crossbreeding, sometimes called "#designercrossbreeding", is the process of breeding such an organism, often with the intention to create offspring that share the #traits of both parent lineages, or producing an organism with #hybrid vigor. While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of #inferiorquality or #dilute a purebred gene pool to the #pointofextinction of a given breed of organism. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. #Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding The multiple failures and fiascos of the War of 1812 convinced Washington that thorough reform of the War Department was necessary. Secretary of War, John C. Calhoun reorganized the department into a system of bureaus, whose chiefs held office for life, and a commanding general in the field, although the Congress did not authorize this position. Winfield Scott became the senior general until the start of the American Civil War in 1861. The bureau chiefs acted as advisers to the Secretary of War while commanding their own troops and field installations. The bureaus frequently conflicted among themselves, but in disputes with the commanding general, the Secretary of War generally supported the bureaus. Congress regulated the affairs of the bureaus in detail, and their chiefs looked to that body for support.
Calhoun set up the Bureau of Indian Affairs in 1824, the main agency within the #WarDepartment for dealing with Native Americans until 1849, when the Congress transferred it to the newly founded Department of the #Interior. American Civil War to 1898Edit
