Displaying returned array as radio buttons

Question

I'm trying to display a set of radio buttons (male or female) on my index page. Within my Form I build the form like this:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
    ->add('gender', ChoiceType::class, array(
        'choices'  => array(
            'Male' => 1,
            'Female' => 2,
        )));
}

Then within the Controller:

public function indexAction(Request $request)
{
    $participantEntry = new Participants();

    $form = $this->createForm(ParticipantsType::class, $participantEntry,[
        'action' => $request->getUri()
    ]);

    $form->handleRequest($request);

    return $this->render('SurveyBundle:Page:index.html.twig',
        ['form' => $form->createView()]);

}

However, I'm not sure how to actually display as RadioButtons within my Twig file, this is what I've tried:

{% for g in form.gender %}
    {{ g.value }}
{%  endfor %}

BTW: The $gender within my Entity is an int

Which doesn't work, does anyone know what I am doing wrong?

Change the add into builder as follow

->add('gender', ChoiceType::class, array(
    'choices'  => array(
        'Male'   => 1,
        'Female' => 2,
    ),
    'expanded' => true,
    'multiple' => false 
);

The combination of 'expanded' => true and 'multiple' => false will generate radio buttons, then in twig, just use

form_widget(form.gender)
