What are the characteristics of an animal with 100% CI?
An animal with a CI of 100% is equivalent to a member of an inbred line. Such lines have been produced in laboratory animals such as mice, but only after losing many lines (typically more than 90%) due to inbreeding depression. In animals with 100% CI, every section of every chromosome has two identical copies of the same segment of DNA (in technical terms, such animals are completely homozygous). This means that every sperm and every egg produced by such an animal is identical. Because of this, animals with 100% CI are said to be true-breeding, although in reality there is still variation in their offspring, due to new mutations and variation in non-genetic factors.
