This is how I solved my problem

I just add three fields in my table

1- ISMALE
    
    2- ISFEMALE
    
    3- COMMON

And make COMMON True if both male and female statuses are in common.

And make ISMALE True and ISFEMALE False for male statuses.

And make ISFEMALE True and ISMALE False for female statuses.

**VB Code**

    Protected Sub ddlSexType_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSexType.SelectedIndexChanged
        Try
    
            Dim context As New EGrantsModel.Entities
            If (ddlSexType.SelectedValue = "Female") Then
                Dim femaleDataSource As Object
                femaleDataSource = (From femaleDS In context.CITIZENSTATUS _
                                    Where femaleDS.ISFEMALE = "1" And femaleDS.ISMALE = "0" AndAlso femaleDS.COMMON = "1"
                                    Select femaleDS)
                ddlCitizenStatus.DataSource = femaleDataSource
                ddlCitizenStatus.DataValueField = "CITIZENSTATUSID"
                ddlCitizenStatus.DataTextField = "CITIZENSTATUS"
                ddlCitizenStatus.DataBind()
            ElseIf (ddlSexType.SelectedValue = "Male") Then
                Dim maleDataSource As Object
                maleDataSource = (From femaleDS In context.CITIZENSTATUS _
                                    Where femaleDS.ISFEMALE = "0" And femaleDS.ISMALE = "1" AndAlso femaleDS.COMMON = "1"
                                    Select femaleDS)
                ddlCitizenStatus.DataSource = maleDataSource
                ddlCitizenStatus.DataValueField = "CITIZENSTATUSID"
                ddlCitizenStatus.DataTextField = "CITIZENSTATUS"
                ddlCitizenStatus.DataBind()
            End If
        Catch ex As Exception
            callErrorPage(ex.Message, ex.InnerException)
        End Try
    End Sub

I am really new to VB, so if someone think that this a lengthy approach then kindly update me for a better approach.
