In mice the allele for colour expression is C (c= albino).Another gene determines colour (B= black, b= brown). Yet another gene modifies the amount of colour sothat D= normal amount of colour and d= dilute (milky) colour. Two mice that are CcBbID aremated.
a. What proportion will be dilute brown?
b. What is the name of the type of interaction seen between gene Dand gene B?
