what if i does not include name="gender" in the form

Answer 1

If you don't specify a name attribute in a radio button, you will be able to select more than one option and u won't be able to unselect the selected options, while a radio button should only accept one option. Helpful?

Answer 2

While in a checkbox, there won't be any physical difference. But you will not be able to collect information from the checkbox without a name attribute.
