Despite problems with the homozygous recessive, some unscrupulous breeders continue to breed them together because of the high prices they fetch. A. The BC gene causes a mutation in a growth gene. B. The BC gene and a gene for growth are very close to one another on the same chromosome. C. The BC gene and a gene for growth are both mutated. D. The dominant version of the cheek color gene (GC) encodes a gene for normal size. E. The BC gene and growth gene are close together on the same chromosome and/or both of these genes are mutated.
