+            Args:
+                solution (list): A solution containing genes, potentially with duplicate values.
+                gene_index (int): The index of the gene for which to find a unique value.
+                min_val (int): The minimum value of the range to sample a number randomly.
+                max_val (int): The maximum value of the range to sample a number randomly.
+                mutation_by_replacement (bool): Indicates if mutation is performed by replacement.
+                gene_type (type): The data type of the gene (e.g., int, float).
+                step (int, optional): The step size for generating candidate values. Defaults to 1.
 
             Returns:
-                selected_value: The new value of the gene. It may be identical to the original gene value in case there are no possible unique values for the gene.
+                int: The new value of the gene. If no unique value can be found, the original gene value is returned.
