The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Chromosome number: Total number of chromosomes in all sets combined ... each potato plant inherits two sets of 12 chromosomes from the pollen parent, and two sets of ...
Polyploid plants can arise spontaneously in nature by several mechanisms, including meiotic or mitotic failures, and fusion of unreduced (2n) gametes. [41] Both autopolyploids (e.g. potato [75]) and allopolyploids (such as canola, wheat and cotton) can be found among both wild and domesticated plant species.
In 2009 a draft sequence of the potato genome was made, containing 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. [ 24 ] It had been thought that most potato cultivars derived from a single origin in southern Peru and extreme Northwestern Bolivia , from a species in the S. brevicaule complex.

Ethephon, a plant growth regulator product that is converted to ethylene after metabolism by the plant, can be used to increase fruit and seed production. [19] [26] Although Cucurbita species can generally produce healthy fruit after pollination from the same plant, inbreeding depression can significantly reduce seed number and fruit size. [27]
An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
