Transposons (or transposable elements) are present only in prokaryotes. edit genes. can disrupt genes. are always in the same place in different strains of the same species. can only affect an organism's genotype, not its phenotype.

Not true. Transposons can be present in eukaryotes too.

Explanation:

They edit and disrupt the genes. They are not are same place of in different strains of same species because they are transposon, they move and change location. Due to what it disrupts, it can affect phenotype but probably change location in nontranscripted places.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
