A scientist shines low levels of ultraviolet radiation on a dish containing colonies of ruby-red bacteria. He then makes several replicate plates from this dish over many generations. He finds that in addition to the ruby-red color, there are also pink, orange, and light red bacteria. Which of the following is the best explanation for these findings?
Based on the following scenario, the best explanation for the findings would be that Mutations occurred in the gene for color of the bacteria ,
Which were passed on to successive generation
Hope this helps
