Different packet types with single sequencer.?

Hi,

  Here I am attaching a sample code for my doubt:

1)  class base_pkt extends uvm_sequence_items;

     -

     -

    endclass

2)  class base1_pkt extends base_pkt;

     -

     -

     endclass

3)  class base2_pkt extends base1_pkt;

     -

     -

     endclass

4) class my_sqr extends uvm_sequencer#(base_pkt);

     -

     -

     endclass

    There are sequences for each packet like seq_base_pkt, seq_base1_pkt, seq_base2_pkt.

    The corresponding transaction types provided for the sequences.

    Q:- When I run this code by adding required structure. Can I be able to generate all packets to driver through sequencer..?
