Epistasis is where one gene hides the effects of another gene. In labrador dogs, the dominant allele (E) determines whether the skin will have pigment. The dominant allele (B) determines how dark it is (color). Match the color dog with the correct genotype. Black lab Chocolate (brown) lab Yellow lab

Assume that you are interested in separating short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range. you have two recipes for making your polyacrylamide gels: one recipe uses 1.5 percent agarose and would be considered a “hard gel,” while the other uses 0.5 percent agarose and would be considered a loose gel. which gel should you use to separate the short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range?
