• only the agouti allele on the same chromosome as the As allele is affected
• the expected cream belly is not seen for this genotype; the mouse looks normal agouti

• only the agouti allele on the same chromosome as the As allele is affected
• the expected cream belly is not seen for this genotype; the mouse looks normal agouti
