Mutations are spontaneous variations to nucleotide sequences, therefore in two animals or two chromosomes they can not be identical by nature. Therefore, the introns interact with non-coding sequences and therefore their sequences are not established as consensus in nature and are therefore highly prone to mutations.
Each body cell contains the same number and kinds of chromosomes for that organism. The chromosomes contain the same number and kinds of genes for that individual.
