They may be favored due to their compact size, fertility, quick gestation time period and ease of managing and mainly because they are liable to many of the disorders and bacterial infections that afflict individuals. They're Employed in analysis into genetics, developmental biology, mobile biology, oncology and immunology.[137] Guinea pigs had been well-known laboratory animals right until the late twentieth century; about 2.
These burrowing animals reside in underground colonies of as many as 80 men and women. A dominant female (a queen) breeds by using a number of breeding males, though the remaining ladies while in the team are sterile and performance as employees only.
