A PCR reaction amplifies two DNA fragments from a genomic DNA
template. All of the following could explain this observation
EXCEPT:
Group of answer choices
The individual was heterozygous for two different sized
alleles.
The denaturation temperature was too low decreasing
specificity.
The primers were not specific and amplified two different
sequences.
The reaction was contaminated with a foreign source of DNA.
The annealing temperature was too low decreasing
specificity.
