the organism's environment
Not all are that harmless. Sickle cell disease is a point mutation. A missense mutation can be harmful, but substituting one purine base for another, or having the same type of amino acid, hydrophobic to hydrophobic for instance, made is not harmful.
Well, in some ways they are harmless because they are just a set of nucleotides that didn't pair up properly during DNA replication. They are mostly harmless because sometimes when the DNA is changed, the organism with the mutation will benefit from the different characteristics. For ex: a sparrow with a short beak cannot reach the worm in the tree. A sparrow with a genetic mutation, or a long, narrow, beak can benefit because it has the proper beak to reach the worm in the tree. Most mutations don't affect how an organism looks or functions at all, because many of the changes that occur due to mutations happen in parts of the DNA that never get expressed.
Assuming the deleterious trait is recessive, the individual would be called a carrier.
Well, you can think of bacteria. Many cause diseases. For example, 2 bacteria that damage the stomach is Heliobacter Pylori and E.Coli.
