A hypothetical brown frog with black spots (genotype BbSs) is test crossed with a green, unspotted frog (genotype bbss). These produce the following progeny: brown + spotted: 64 brown + unspotted: 134 green + spotted: 130 green + unspotted: 72 a. What is the genotype of the original dihybrid frog? Specify which alleles are on each chromosome of the brown frog with black spots (i.e. AB/ab or Ab/aB). b. How many map units separate the colour and spot genes? Show your calculations.
