The possibility of magnifying contaminating sequences present in a nucleic acid pool is a drawback associated with PCRs high level of sensitivity (i.e., potential for exponential amplification). True or False?
Ans : True
Reason : Since PCR is a highly sensitive technique as it allows for the amplification of a specific DNA fragment from a complex pool of DNA.Any form of contamination of the sample, a trace amounts of DNA can give you a misleading results.

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
