Answer:
DNA is one of the major sources might be wrong tho
Explanation:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
By using microarray technology you can calculate the ratio by analyzing the colors on the glass plate. If the ratio is greater than 1, then the gene is induced by tumor formation. Less than 1 then it is suppressed by tumor formation. If the ratio is 0, the gene is not expressed in either cell. If the ratio is =<span> to 1, the gene is not affected.</span>
<span>Allele frequency is a factor within a population that can be studied in order to determine whether or not a population is evolving. Alleles are one of two or more ways in which a particular gene can be expressed. One can measure this expression in a population and measure its frequency to measure whether or not the population is evolving.</span>
Gene therapy is correct I'm pretty sure
