Which of the following might lead to the generation of several incorrect pcr products?

An annealing temperature that is too low

Explanation:

The annealing temperature (Ta) chosen for pcr relies directly on length and composition of the primers. Generally, you should use an annealing temperature about 5°C below the Tm of your primers. An optimal annealing temperatures give the highest product yield of the correct amplicon. An amplicon is a piece of DNA or RNA that is the source and/or product of amplification or replication events. It can be formed artificially, by either using various methods in polymerase chain reactions (PCR) or ligase chain reactions (LCR), as well as, naturally through gene duplication.

In an aquatic environment a plant would have access to mostly blue an cyan colors of light at around 450-495 NM wavelength. if the plant contained many pigments that absorbed red light, that a plant could rarely gain access to, the plant would not be able to absorb enough light to undergo photosynthesis . The plant would most likely not be able to reproduce before it died, but if a plant had many photo pigments that would absorb blue light (which is plentiful in its environment) then the plant would thrive. it could pass on its genes and its offspring would have a higher fitness than plants that could only absorb red light. The remaining plants would only use the blue colors of the visible light spectrum because it wouldn't be efficient to have pigments that could absorb red light.
