In the presence of ii the coat color is black due to the dominant gene B, or brown due to the recessive gene b. Two dogs both having the Bbli genotype were mated. Answer the following questions and show complete solutions to support your answers. Use the branching method whenever applicable. What is the phenotypic ratio of the offspring? What type of gene interaction is exhibited by the coat color in dogs? What would be the probability of getting dogs that are pure-breeding for a black coat color? 3. a. b. C.1. Chinchillas are small, furry South American rodents. They were originally brought to the United States from Chile in 1918 and raised for their fur, and have become increasingly popular as cage pets.
