  1. Rabbit Genetics

  2. Coloration of Netherland Dwarfs • 5 Genes provide the total coloration • A – Agouti • B – Black-Chocolate • C – Color • D – Dilute/Dense • E - Extension

  3. Agouti • Agouti gene is responsible for determining whether a mammal’s coat is banded (agouti) or solid color (non-agouti) • “A” gene is in 3 forms: • A = agouti • at = tan • a = self

  4. Black-Brown • This gene controls if the fur will be in the black family of brown family • Black fur is Dominant • BB • Bb • Brown fur is Recessive • bb

  5. Color Gene • There are 5 main color genes that determine the color of a rabbit’s fur. (Our dwarfs only exhibit 2 types) • Full Color – Dominant • C - C • C – ch • C – cchd • C - c • Himalayan – color only in muzzle, ears, and feet; rest is pure white • Ch – Ch • Ch - c

  6. Dilute/Dense • Controls the pigment in the fur • Dense = strong color and is dominant • DD • Dd • Dilute = lighter color and is recessive • dd

  7. Extension • Extended • Controls if the main fur color goes from the tip of the hair to the base • Dominant • EE • Ee • Non-extended • The Main fur color only goes part way down the hair and a second color starts • Recessive • ee
