    To check or uncheck a checkbox or radio button,  Jquery support some method for you resolved this problem. You can use attr() or prop() methods to do. Notice two methods can check and uncheck for both radio and checkbox buttons.

    1. To set checked a radio or checkbox button.

    $( "#male").prop( "checked", true); 


     $( "#male").attr( "checked", true); 

    2. To unchecked a radio or checkbox button.

     $( "#male").prop( "checked", false ); 

    Same as checked a radio or checkbox, you only set true to a false value to uncheck it.

    You also use javascript to check or uncheck a radio & checkbox button:

     document.getElementById("male").checked = true; 

    I hope these answers helpful to you.
