            <item name="config" xsi:type="array">

                    <item name="required-entry" xsi:type="boolean">true</item>
                </item>

    </field>

Create > [vendor]/[module]/Model/Config/Source/Gender.php

namespace [Vendor]\[module]\Model\Config\Source;

use Magento\Framework\Option\ArrayInterface;

class Gender implements ArrayInterface
{
    /**
     * @return array
     */
    public function toOptionArray()
    {
        $options = [
            0 => [
                'label' => 'Male',
                'value' => 'male'
            ],
            1 => [
                'label' => 'Female',
                'value' => 'female'
            ],
        ];

        return $options;
    }
}
