here is your code 

 protected void Page_Load(object sender, EventArgs e)
{

    if (!IsPostBack)
    {
        PanelFirstQuestionBlock.Visible = true;
    }
}

protected void FirstQuestionGotAnswered(object sender, EventArgs e)
{
    PanelFirstQuestionBlock.Visible = false;
    PanelSecondQuestionBlock.Visible = true;
}

here your ASP:HTML

<asp:Panel ID="PanelFirstQuestionBlock" runat="server" Visible="false">
        <h1>My first Question</h1>
        <asp:RadioButtonList ID="RadioButtonListAnswer1" runat="server" 
            OnSelectedIndexChanged="FirstQuestionGotAnswered">
            <asp:ListItem>yes</asp:ListItem>
            <asp:ListItem>no</asp:ListItem>
        </asp:RadioButtonList>
    </asp:Panel>

    <asp:Panel ID="PanelSecondQuestionBlock" runat="server" Visible="false">
    <h1>My second Question</h1>
        <asp:RadioButtonList ID="RadioButtonListAnswer2" runat="server">
            <asp:ListItem>yes</asp:ListItem>
            <asp:ListItem>no</asp:ListItem>
        </asp:RadioButtonList>
    </asp:Panel>

You should place third entry between:

<%
    if (needToShowThirdEntry) {

%>

and

<%
  }

%>

So, your code:

<asp:RadioButtonList ID="selectdYesNo" runat="server" RepeatDirection="Horizontal">
     <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
     <asp:ListItem Text="No" Value="0"></asp:ListItem>
  <%
    if (needToShowThirdEntry) {     
  %>
     <asp:ListItem Text="Maybe" Value="2"></asp:ListItem>
  <%
   }        
  %>
</asp:RadioButtonList>

UPDATE As you updated your question, my new answer would be:

<asp:RadioButtonList ID="selectdYesNo" runat="server" RepeatDirection="Horizontal">
            <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
            <asp:ListItem Text="No" Value="0"></asp:ListItem>
</asp:RadioButtonList>


  <%
    if (needToShowSecondList) {     
  %>
<asp:RadioButtonList ID="newRBList" runat="server" RepeatDirection="Horizontal">
     <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
     <asp:ListItem Text="No" Value="0"></asp:ListItem>
     <asp:ListItem Text="Maybe" Value="2"></asp:ListItem>
</asp:RadioButtonList>
  <%
   }        
  %>

But, as this is separate list, you should make normal radio button list (without if) and use newRBList.Visible property from code behind to hide it on first rendering (before postback)

you can try like this selectdYesNo.Items.Add(new ListItem("text","value"));
