Imagine that you are studying the control of beta-globin gene’s expression in immature red blood cells (mature red blood cells contain beta-globin protein but lack a nucleus and therefore the beta-globin gene). If you deleted a sequence of DNA outside the protein-coding region of the beta-globin gene and its promoter, and found that this decreased the rate of transcription, the deleted sequence likely functioned as a (n) _____.

In rabbits, there is a gene that controls ear length, with a dominant allele “T” for long ears and a recessive allele “t” for short ears. At another gene locus, there are alleles “B” for black coat and “W” for white coat. Neither the B or W allele is dominant, and BW produces a gray coat. These two allele pairs assort independently. If a gray rabbit that is heterozygous at the gene locus controlling ear length is mated with a white rabbit that is also heterozygous at the gene locus controlling ear length, what is the probability that their first offspring will be gray with long ears?
