Oops!  That should be

individual1 = RandomPermutation[12]
individual2 = RandomPermutation[12]
cutPosition = 3;
cutLength = 4;
cutSequence = Take[Drop[individual1, cutPosition], cutLength]
sonOne = DeleteCases[individual2, _?(MemberQ[cutSequence, #] &)]
sonOne = RotateLeft[sonOne, 1]
sonOne = Join[Take[
      sonOne, cutLength - 1], cutSequence, Drop[sonOne, cutLength - 1]]

Complement returns a sorted result, and you didn't want that.

Here's an answer to Question 1:

individual1 = RandomPermutation[12]
individual2 = RandomPermutation[12]
cutPosition = 3;
cutLength = 4;
cutSequence = Take[Drop[individual1, cutPosition], cutLength]
sonOne = Complement[individual2, cutSequence]
sonOne = RotateLeft[sonOne, 1]
sonOne = Join[Take[sonOne, cutLength - 1], cutSequence, Drop[sonOne,
     cutLength - 1]]

Dear Group,

     It is a pleasure write to you again. I have three questions to ask.

Thanks for any enlightenment on these subjects.

                                            Alexandre Costa

    

Question One: The below code is working fine but I think there are more 
elegant ways of doing so.

Any suggestions are VERY WELCOME.

<< DiscreteMath`Permutations`

individual1 = RandomPermutation[12]
individual2 = RandomPermutation[12]

CutPosition = 3 ;
CutLength = 4 ;
CutSequence = Take[Drop[individual1, CutPosition], CutLength]

SonOne = individual2;
Do[
    If[MemberQ[SonOne, CutSequence[[i]]],
      SonOne = Delete[SonOne, Position[SonOne, CutSequence[[i]]]]], 
{i, 1,
      CutLength}];
SonOne
SonOne = RotateLeft[SonOne, 1]
Do[SonOne = Insert[SonOne, Reverse[CutSequence][[i]], CutPosition + 
1], {i, 1,
     CutLength}]
SonOne

Question Two:

How can I change points properties (such as Size and Color) for the plot

below?  The PlotStyle Option does not work for this LabeledListPlot

<< Graphics`Graphics`

listcities = {{1, 5}, {4, 6}, {7, 5}, {5, 4}, {9, 4}, {2, 3}, {4, 2}, 
{6, 2}, {1, 1}, {5, 1}, {3, 0}, {9, 0}};

LabeledListPlot[listcities, Axes -> None, Frame -> True,
  GridLines -> Automatic, PlotRange -> All,
  DisplayFunction -> $DisplayFunction]

Question Three: Why the Goto statement below is not working?

q = 2;
Label[start];
q  = 3;
Label[begin];
Print[q];
q += 1; If[q < 6, Goto[begin], Goto[start]]
