Query when ran is not deleting records in table

[rdev]

I have a table called tblapprovedquote with fields App_Num and Quotation_num
I have another table tblquotation with fields Quotation_num and Voy_Num
Both tables are related in a in a one-to-one relationship . I have a query which pulls fields App_Num , Quotation_num from the tblapprovedquote and Voy_num from tblquotation , The query works
But when I delete the records in the query , it is not deleting records in the tblapprovedquote .
What could be the reason

Do you have cascade deletes turned on in the relationships?
