Senior 4-H Rabbit Practice Exam 2026 - Free Practice Questions and Study Guide

Rabbits have a gene called "chinchilla gene" that is responsible for their solid coat color. The gene is dominant, meaning that even if a rabbit only carries one copy of it, they will have a solid coat. However, the "charlie gene" that causes a rabbit's characteristic color pattern is recessive, and a rabbit needs to inherit two copies of it in order to have the pattern. This means that a "charlie rabbit" is always genetically impossible to have solid offspring, regardless of being bred with a solid rabbit, having rare mutations, or being genetically modified. Therefore, option B is the correct answer as it correctly explains that a "charlie rabbit" is unable to produce solid offspring due to not carrying the necessary gene.
