如何使单选按钮每组只能 select 1 个选项？

Question

我有 5 个单选按钮组。我希望用户只能 select 每个无线电组中的一个部分。我的第一组工作正常，只 selecting 一个部分，但是当我 select 某些东西而不是 selected 按钮从 1 移动到另一个 selects 时，其他组部分。

我的代码是：

<html>
<head>
<title> Checkboxes and radio buttons assignment 4 </title>
</head>
<body>

<form name=form1>

<h2>Complete the following</h2>
<hr>
Tick the box if you have the following:
<h2>History of Hereditary Disease </h2>
Heart <input type="checkbox" name=chkHeart value="Heart"> <br><br>
Asthma <input type="checkbox" name=chkAsthma value="Asthma"> 

<br><br>
Arthritis <input type="checkbox" name=chkArthritis 

value="Arthritis">
<br>
<hr>

Select the button that describes you:
