There are nine coat colors known in foxes. If a red

fox were crossed with a double-black fox, all the hybrids would be red above and black below in a pattern known as blended cross. If two blended crosses were mated, the F2 ratio would be as follows: 1 red, 2 smoky red, 2 cross red, 4 blended cross, 1 standard silver, 2 substandard silver, 1 Alaskan silver, 2 sub-Alaskan silver, and 1 double black. (a) Using the letters A/a and B/b to serve as the genes for these animals, develop a genotype for each variety listed. (b) Two crosses will produce all blended-cross offspring. One is used above (red fox x double black); what is the other? (c) List the genotype and phenotype of all the pure-breeding foxes. (d) Give the genotypic and phenotypic ratio of a cross between two substandard silvers. (e) Give the genotype and phenotype of the offspring produced in a cross of a sub-Alaskan silver and a cross red. What will be an ideal response?
