Scientists discover that colder climates, areas averaging 0 to 15°C, trigger a "bleaching effect" on the epistatic gene E/e. This gene works in conjunction with the fur color gene B/b in Labrador retrievers. In more temperate climates, the (B) black fur gene dominates the (b) brown fur gene so that only the (bb) genotype produces brown Labs. In contrast, the E/e gene, which determines how much pigment gets deposited on the fur, is altered chemically by sustained cold weather. Normally, the dominant expression of this pigment gene (EE or Ee) allows the black or brown pigment to adhere to the fur. In warm climates, the recessive allele combination, (ee), alters pigmentation to produce only yellow Labs. The bleaching effects that colder climate has on pigmentation expression may be expressed as: (EE) no effect on pigmentation; black or brown fur depends on the fur coat genotype. (Ee) slight bleaching on pigmentation. Black fur changes to roan (reddish-brown) fur, and brown fur becomes gray. (ee) total bleaching effect on pigmentation; yellow fur now appears white. Mr. Johnson has an entire breeding stock of heterozygous black Labs (BbEe). He wants to breed his animals in a location that can take advantage of this environmental change on the new coat colors produced. If Mr. Johnson moves to Alaska, what color of Labrador retriever can he expect to produce the least of in his first generation of offspring?
