How is a pureline in an animal raised? Explain.

Answer

In animals, a pureline is raised by inbreeding, as inbreeding increases homozygosity.
Inbreeding refers to the mating of more closely related individuals within the same breed for 4-6 generations.
It can be overcome by mating the selected animals of the breeding population with unrelated superior animals to the same breed, i.e. outcrossing.
