This document discusses rabbit coat color genetics. It focuses on the A locus gene, which determines if a rabbit will be solid colored or agouti (wild) colored. The father rabbit is a heterozygote (Aa) and agouti, while the mother is homozygous recessive (aa) and solid black. A Punnett square shows that 50% of offspring will be heterozygous (Aa) and wild colored, while 50% will be homozygous recessive (aa) and solid colored. The actual offspring consisted of 3 wild rabbits and 2 solid rabbits, matching the expected 60/40 ratio.

Coat Color 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.
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
Father Father Heterozygote Aa - Agouti
Mother Mother Homozygous Recessive aa - Solid (Black)
Punnet Square Mother Father A a a Aa aa a Aa aa
Expected Colors & Percentages Mother Father A a a Aa aa a Aa aa 2/4 - Aa Heterozygous (50%) Wild color 2/4 aa Homozygous Recessive (50%) Solid
Resulting Offspring 3 Wild - 2 Solid (60%/40%)
Father Chestnut (Aa-B-Ccch-Dd-E) Mother Blue (aa-B-Ccch-dd-E Opal (Aa-B-C-dd-E) Chinchilla (Aa-B-cchcch-Dd-E) Blue (?) (aa-B-C-dd-E) Squirrel (?) (Aa-B-cchcch-dd-E) Blue (aa-B-C-dd-E) Black (aa-B-C-D-E) Blue (aa-B-C-dd-E)
