The adult flies that emerged had a eyeless mutation phenotype in Drosophila produces greatly reduced eyes.. When this eyeless fly was crossed to a known reduced eye  mutant fly, all the progeny had normal phenotype. The observed phenotype can be best explained as an example of__

Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.
