In peach growing areas, increases in resistance levels could therefore result from advantageous genes spreading through a panmictic population and clonalexpansion. Recent evidence suggests that haemangiomas originate from the clonalexpansion of a progenitor cell. Thus, two independent investigations suggest that haemangiomas may arise as a consequence of clonalexpansion from a single cell. Weber (1985) analysed hundreds of field-collected individuals and found no evidence of clonal expansion, concluding that there was a wide array of different gene combinations. Failure to find a clonalexpansion in this study might be a result of inadequate sampling, as bronchoalveolar lavage fluid rather than tissue biopsies were examined.

Alternatively, clonal expansions might have been present at a frequency that was below the detection of the assay. The presence of clonal expansions of such virus-specific cells may shrink the available repertoire for other antigens, thus filling the 'immunological space'. These clonal expansions are important for at least two reasons. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
