Try below code and let me know if you are still facing issue,

<CheckBox x:Name="chkone"
          Content="QA Review Mandatory" Margin="22,12,289,275"
          IsChecked="{Binding Ischkone}"/>

<CheckBox  x:Name="chktwo"
           Content="Question Mandatory" HorizontalAlignment="Left"
           Margin="22,85,0,201" >                
   <CheckBox.Style>
                    <Style TargetType="CheckBox">
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=chkone,Path=IsChecked}" Value="True">
                                <Setter Property="IsChecked" Value="True"/>
                                <Setter Property="IsEnabled" Value="False"/>
                            </DataTrigger>
                            <DataTrigger Binding="{Binding ElementName=chkone,Path=IsChecked}" Value="False">
                                <Setter Property="IsChecked" Value="False"/>
                                <Setter Property="IsEnabled" Value="True"/>
                            </DataTrigger>
                        </Style.Triggers>
                    </Style>
                </CheckBox.Style>
            </CheckBox>
