Which of the following is a sign of potential anatomical disqualifications in rabbits?

Extra toes are a clear sign of potential anatomical disqualifications in rabbits because they indicate a genetic anomaly that deviates from the standard characteristics defined for each breed. Each recognized breed of rabbit has specific standards regarding their anatomical features, and any significant deviation, such as the presence of additional toes, can disqualify a rabbit during competitions and breeding assessments.

In contrast, factors like fur color, body weight, and ear length may be important for determining the conformity of a rabbit to breed standards, but they do not inherently suggest a disqualifying anatomical defect. For instance, while fur color is a key characteristic, it varies widely among breeds and isn’t typically grounds for disqualification unless it specifically contradicts breed standards. Similarly, body weight is assessed for conformity but can sometimes be remedied with proper management. Ear length is also breed-specific but does not signal an anatomical defect in the same way that extra toes do.
