Question

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.
Solanum
microdontum
36
The basic
chromosome number
(x) for these species
is 12.
S. microdontum could
have arisen only from
a cross between S.
avilesii and S.
tuberosum.
False
Solanum
tuberosum
48
S. microdontum could
have arisen from a
cross between S.
avilessi and S.
tuberosum.

Introduction

As a flowering plant (angiosperm), the potato (Solanum tuberosum) is traditionally categorized as the following: Plant Kingdom, flowering plant phylum (Magnoliophyta = Anthophyta), dicot class (Eudicot class), potato order (Solanales), potato family (Solanaceae).

The herbaceous potato has a normal plant structure, consisting of above-ground branches with leaves and underground roots. The above-ground stem and leaves of this plant, like tulips and a handful of others, are "annual," or they wither and die every year. The plant is perennial because a section below the earth lives and continues to support the organism. A structure known as a tuber, a branch shoot that develops and persists underground, is the perennating component.
