Yes.

Yes.

A Structure is a type of Variable that contains other Variables,
analogous to a struct in C, or a row in a relational database. In
general, the data in a Structure are physically stored close
together on disk, so that it is efficient to retrieve all of the
data in a Structure at the same time. A Variable contained in a
Structure is a member Variable, and can only be read in the
context of its containing Structure.

Opening your dataset in the netCDF-Java ToolsUI [1] "NcDump" tab, I get the 
following

{

  group: Chromosomes {
    variables:

      Structure {
        byte Chromosome;
            :_Unsigned = "true";
        int Display_&size;
        char Display(4);
        int StartIndex;
            :_Unsigned = "true";
        int MarkerCount;
            :_Unsigned = "true";
        float MinSignal;
        float MaxSignal;
        float MedianCnState;
        float HomFrequency;
        float HetFrequency;
        float Mosaicism;
        float LOH;
        float MedianSignal;
      } Summary(24);
  }
  ...
}

netCDF has two data models:

1) The netCDF-3 data model ("classic") was made up of files, dimensions, 
attributes, and variables where the variables were simple multi-dimensional 
arrays.

2) 
Here is a snippet from the netCDF enhanced data model
