In The Hobbit, there is clearly a mention of Orc reproduction by setting up Bolg as "the son of Azog". Not only is he a biological son, he also inheirits Azog's position and power, which implies that Orcs recognize and attach importance to biological lineage/parentage that can only arise from sexual reproduction. But by the time he writes the Lord of the Rings, Tolkien's views seem to have changed, because Orcs no longer seem to have "sons" but are "bred" by an overseeing power, be it Sauron or Saruman. It is nowhere mentioned that an Orc has a family; a son or a father, or anything else. It seems rather that they were mass-bred like clones. Here's some more food for thought: why did Tolkien's description of Orc-breeding change from The Hobbit to LOTR?
Clearly seeking an immediately understandable and visual answer for this issue, Peter Jackson interpreted Uruk-hai "breeding" as Uruks emerging fully grown from sacs in the ground. The Uruks were supposedly crossbreeds between Men and Orcs, but that again doesn't make sense because we know Men reproduce sexually. How could an asexual and a sexual species "breed"?
In The Lord of the Rings, the Orcs belonged to three main factions: the Mordor Orcs, the Misty Mountain Orcs, and the Isengard Orcs. In the chapter "The Uruk-hai" from The Two Towers, these three factions come into conflict over what to do with their captives, Merry and Pippin.
Mordor Orcs besieged Minas Tirith and defended the Black Gate in The Return of the King. Mordor Orcs were larger and tougher than most other Orcs, although not to the extent of Saruman's Uruk-hai. In the chapter "The Bridge of Khazad-dûm" from The Fellowship of the Ring, Gandalf said that the Mordor Orcs were "large and evil" in comparison to the other Orcs in Moria. In the novel, the Mordor Orcs painted red eyes on their armor and shields, representing the Eye of Sauron. For this reason, they were also known as Orcs of the Eye. Other Orcs believed that Mordor Orcs were cowardly and untrustworthy. In "The Uruk-hai," Uglúk told Grishnákh, "I don’t trust you little swine. You’ve no guts outside your own sties. But for us, you'd all have run away."
