The effect differs. It could produce a different amino acid in the sequence because the corresponding codon has changed. It could also prevent the production of the originally intended sequence by changing one of the amino acids of a "start" codon (aka AUG) or extend the protein's sequence by modifying a "stop" codon (UAA, UAG, UGA or UGG), producing a new protein that might be useless or have different effects on the cell.

Tt is a genotype different than tt. The first one has two different alleles (T and t) the second one has one kind of alleles (t).
The fenotype of Tt is given by the dominant character (which is the capitalized one, T) while the fenotype of tt is t (because it is the only one).
Then, there are two different genotypes and two differente phenotypes.
Answer: The two have different genotypes and different phenotypes.
Myelin sheaths are found on the outside of nerve cells. They protect the sensitive axons underneath like how insulation protects wires.
