How to create groupbox element click Listner in c#

I have groupbox with 2 element inside it. I want, when I click on one element inside group box then other element should be deselected. I can do it by making separate listener for all element. Like this.

private void maleBox(object sender, MouseEventArgs e)
        {
            if (femaleCheckBox.Checked)
            {
                femaleCheckBox.Checked = false;
            }
        }

        private void femleBox(object sender, EventArgs e)
        {
            if (maleCheckBox.Checked)
            {
                maleCheckBox.Checked = false;
            }
        }

But I want a single click listener which handle it.
