Which term describes a breeding system that strictly adheres to established standards and breeds?

The term that describes a breeding system that strictly adheres to established standards and breeds is purebred breeding. This system focuses on maintaining a consistent genetic line or breed by only mating animals of the same breed with recognized pedigree. Purebred breeding is essential for preserving desired traits and characteristics within a breed, ensuring that offspring inherit the qualities that define that specific breed.

In contrast, linebreeding involves mating individuals from the same breed but may include ancestors that are more distantly related, allowing for some genetic variability while still focusing on specific desirable traits. Inbreeding refers to mating closely related individuals, which sometimes leads to an increase in genetic defects due to the lack of genetic diversity. Selective breeding involves choosing parents based on their specific traits to produce offspring that carry those traits but does not necessarily adhere strictly to established breed standards.

By adhering to defined standards and utilizing genetic lineage, purebred breeding ensures the integrity and recognizable qualities of a breed, making it the appropriate term for the definition provided.
