Question

coelatura is a genus of freshwater mussels. a researcher collects five species of coelatura from the nile river. the researcher takes dna samples of each species and performs gel electrophoresis to find genetic similarity between the species. the diagram shows the results of the gel electrophoresis. coelatura gel electrophoresis select the two pairs of species that share the greatest genetic similarity based on the results of the gel electrophoresis. c. aegyptiaca - c. gallardoti and c. parreyssi - c. canopicus c. aegyptiaca - c. prasidens and c. gallardoti - c. parreyssi c. gallardoti - c prasidens and c. aegyptiaca - c gallardoti c. parreyssi - c. canopicus and c. gallardoti - c prasidens

Explanation:

Gel electrophoresis separates DNA fragments. The more similar the banding patterns (number and position of bands), the greater the genetic similarity. For \(C. gallardoti - C. prasidens\), they have two bands of the same size (approx \(5090\) and \(4072\) base pairs). For \(C. parreyssi - C. canopicus\), they have two bands of the same size (approx \(4072\) and \(3054\) base pairs).

Answer:

C. parreyssi - C. canopicus and C. gallardoti - C. prasidens
