How about this - fiddle: 

<input type="checkbox" class="chk" />
<input type="checkbox" class="chk" />
<input type="checkbox" class="chk" />
<input type="checkbox" class="chk" />

$('input.chk').on('change', function() {
    $('input.chk').not(this).prop('checked', false);  
});

Edit: for second part of your question to un-check other checkboxes when selecting parent checkbox see this fiddle - (as per chat) :

if (!cb.checked) { 
$('#trchkOptions input[type=checkbox]').attr('checked', false); 
}

function selectOnlyThis(id) {
    for (var i = 1;i <= 4; i++)
    {
        document.getElementById(i).checked = false;
    }
    document.getElementById(id).checked = true;
}
<input type="checkbox" id="1" value="Value1" onclick="selectOnlyThis(this.id)" /> Option 1
<input type="checkbox" id="2" value="Value1" onclick="selectOnlyThis(this.id)" /> Option 2
<input type="checkbox" id="3" value="Value1" onclick="selectOnlyThis(this.id)" /> Option 3
<input type="checkbox" id="4" value="Value1" onclick="selectOnlyThis(this.id)" /> Option 4

It should help you
