6 Coat colour in cattle is determined by a set of incomplete dominant alleles. There is an allele that codes for brown hair and an allele that codes for white hair. The heterozygous phenotype is known as "roan" (a beige-like colour that is a mix between brown and white). Perform a test cross between a bull with brown hair and a cow with roan-coloured hair. State the genotypic and phenotypic ratios.
