1. Rabbit Color Genetics

2. Coat Color (Aa-B-Cch-Dd-E)
Coat color in rabbits is controlled by at least 5 known genes. 2 more are suspected.
(Aa-B-Cch-Dd-E)
Our discussion will focus on what is called the A locus.

3. A Locus
The A locus determines whether the rabbit will be solid colored or wild (Agouti) colored. AA – Homozygous Dominant - Wild Aa – Heterozygous – Wild aa – Homozygous Recessive - Solid

4. Father
Father – Heterozygote
Aa - Agouti

5. Mother
Mother – Homozygous Recessive
aa - Solid (Black)

6. Punnet Square
Mother
Father A a Aa aa

7. Expected Colors & Percentages
Mother
Father A a Aa aa
2/4 - Aa Heterozygous (50%) Wild color 2/4 – aa Homozygous Recessive (50%) Solid

8. Resulting Offspring
3 Wild Solid (60%/40%)
