What is "line breeding" in rabbit breeding?

Line breeding is a selective breeding practice aimed at reinforcing desirable traits within a specific line or family of rabbits. This technique involves mating rabbits that are related, but not so closely as to cause inbreeding, such as those that share a common ancestor several generations back. The purpose of line breeding is to maintain genetic continuity while minimizing potential negative effects associated with too close of a relatedness, such as reduced vigor or health complications.

By using this method, breeders can enhance certain qualities—such as coat color, size, or temperament—while still retaining a diverse gene pool to avoid detrimental inbreeding effects. This strategic approach allows for consistent quality in offspring and the preservation of desired characteristics across multiple generations. Unlike the other options, which involve unrelated or overly close matings, line breeding strikes a balance that supports maintaining strong genetic traits while promoting overall rabbit health.
