How to lock an option (form attributes)

Question

Hello guys, currently i am learning about forms in HTML. When i tried to code this way:

<form>
<input type="radio" gender="name" value="male"/> Male <br />
<input type="radio" gender="name" value="female"/> Female <br />
</form>

I found out that both options can be checked -- Male & Female. Is there a way to prevent that? So we can chose only either Male or Female.

Thank you.

Answer 1

name="gender"

Answer 2

<input type="radio" name="gender" value="male" />Male <br />
<input type="radio" name="gender" value="female" />Female <br />

Answer 3
