When I take a dump of network traffic and save in the .pcap file. I load that pcap file in the wireshark for analyzing and what I find is there is a re-transmission of the tcp packet in the wireshark.

Question: What my question is why the re-transmission is showing up in the wireshark. Didnt the TCP took care of the re-transmission.

Yes, that's why you see it. Wireshark shows what was recorded, and if there was packet loss TCP sent a retransmission that got recorded, too. Wireshark is not hiding anything.
