The personal experience of the violin experience due to the regular practising of the violin leads to the increase in the somatosensory representation. This occurs as a result of regular use of the fingers. As the dominant finger is regularly involved in the sensation and the sensory functions, the somatosensory area for the touch of that particular structure is increased.
Metaphase is the stage in which the "crossing over" occurs.
As we know chromosomes carry genetic information. This crossing over process happens in eukaryotic cells and occurs during the mitosis phases of cell division.
