the coat colour in mice is controlled by several genes. the aqout patter characterised by yellow band of pigment near the tip of the hairs is produced by the dominant allele A, homozygous aa mice do not have the band and are non agout. the dominant allele B determine black hair and reccessive allele b determine brown. Homozygous 'chch' individual s allow to pigment to be deposited only at the extremities( eg, feet and toe) in a pattern called Hamilaya. the genotype C- allow pigment to be distributed over the entire body. (a) if the true breeding blabck mouse is crossed with a true breeding brown, agout,Himalayan mouse. what wiilbe the phenotype of F1 and F2 (b) what proportion of the black agout F2 will be of genotype AaBBChch (c) what proportion of the Himalayan mice in the F2 is expected to show brown pigment (d)what proportion of all agoutis in the F2 is expected to shoe black pigment ?
