if the brown mail had been BB then all offspring would have been Bb and all brown however is the male is Bb as above and you perform a test cross 50% of all Offspring should have the bb genotype and a white phenotype a testcross to a heterozygous individual should always yield about a one-to-one ratio of the dominant or recessive phenotype so both of the genotypic and phenotypic ratios here are 50/50
