radio button displayed with background IE Vs Chrome

Whereas in Chrome, it shows the radio buttons without any background square or rectangle

Question 2

How do I get the asterix without having to write it - like <label>Organization  *</label> ? And the asterix should be red in color. It has to happen for <td> content, label and other such control i.e. should display * beside the control I want to and in red color signifying its required field.
