- The table shows three related species of potato, and the number of chromosomes each species carries in its somatic cells. S. avilesii is diploid. S. tuberosum is the widely cultivated species. Potatoes propagate by asexual reproduction and do not depend only on gametes for reproduction. Species Number of chromosomes in somatic cells S. tuberosum is likely to be a larger, more vigorous plant than S. avilesii. Classify each statement about these potato species as true or false. Gametes produced by S. microdontum contain 18 chromosomes. S. microdontum is aneuploid. S. microdontum is a triploid with 3x chromosomes. Solanum avilesii True 24 The basic chromosome number (x) for these species is 6. S. tuberosum is a tetraploid with 4x chromosomes.
