The results shown in the picture were obtained using a technique known as gel electrophoresis. This technique separates mixtures of DNA. In the picture nine different samples of DNA are compared. Gel electrophoresis can be used to - A determine the differences in ages of a set of people B identify how closely two individuals are related С determine how effective certain medications are identify different blood types​

Respuesta :

I would say B ( Identify how closely 2 individuals are related) due to the question being about DNA (genetics- structure of a human and also DNA test results match ur blood related family or biological to be scientific)

Hope this helps!!
