Disclosed are compositions and methods for amplification of nucleic acid sequences of interest. It has been discovered that amplification reactions can produce amplification products of high quality, such as low amplification bias, if performed on an amount of nucleic acid at or over a threshold amount and/or on nucleic acids at or below a threshold concentration. The threshold amount and concentration can vary depending on the nature and source of the nucleic acids to be amplified and the type of amplification reaction employed. Disclosed is a method of determining the threshold amount and/or threshold concentration of nucleic acids that can be used with nucleic acid samples of interest in amplification reactions of interest. Because amplification reactions can produce high quality amplification products, such as low bias amplification products, below the threshold amount and/or concentration of nucleic acid, such below-threshold amounts and/or concentrations can be used in amplification reactions.
