polyploidy 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 solanum avilesii solanum microdontum solanum tuberosum number of chromosomes in somatic cells 24 36 48 classify each statement about these potato species as true or false.

Classify true or false of each statement on potato species

TRUE:

The basic chromosome number (x) for this species is 12
Solanum microdontum is triploid with 3x chromosomes
Solanum tuberosum is a tetraploid with 4x chromosomes
Solanum tuberosum is likely a larger and more hardy plant than S. avilesii
Solanum microdontum may arise from a cross between S. avilessi and S. tuberosum

FALSE:

The number of casic chromosomes (x) for this species is 6
The gametes produced by Solanum microdontum contain 18 chromosomes
Solanum microdontum can only arise from a cross between Solanum avilesii and Solanum tuberosum
Solanum microdontum is aneuploid

Somatic cells are normal body cells other than reproductive cells and take part in the formation of body structures and hence require mitotic cell division which increases the number of diploid cells. Somatic cells are diploid cells, for example, in S. avilesii they have two series of 12 chromosomes, for a total of 24 chromosomes, in each.

Gamete cells are sex cells consisting of ovum cells (egg cells) in females and spermatozoa cells in males. Gamete cells are cells that function for fertilization or fusion. Gamete cells have a haploid number or half of the chromosomes of the body cells. For example, in Solanum microdontum they have they have 24 chromosomes in gamete cells because the somatic cells are 48 chromosomes.
