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.
The potato (/ p ə ˈ t eɪ t oʊ /) is a ... The lenticels are circular and their number varies depending on the size of the tuber and ... containing 12 chromosomes ...
The monoploid number equals the total chromosome number divided by the ploidy level of the somatic cells: 48 chromosomes in total divided by a ploidy level of 4 equals a monoploid number of 12. Hence, the monoploid number (12) and haploid number (24) are distinct in this example.
Polyploid types are labeled according to the number of chromosome sets in the nucleus. The letter x is used to represent the number of chromosomes in a single set: haploid (one set; 1x), for example male European fire ants; diploid (two sets; 2x), for example humans

PacBio and Illumina short‐reads, in combination with 10× Genomics and Bionano data (v1). A total of 949 scaffolds assembled to a final size of 656.77 Mb, with a scaffold N50 of 3.43 Mb (v1), and then further improved to seven pseudo‐chromosomes using Hi‐C sequencing data (v2; scaffold N50: 93.2 Mb, total size in chromosomes: 639.6 Mb).
So, your X chromosome has likely existed for decades before you were even conceived. (One of the many mysteries of the human ovary that doesn’t have a ready explanation.)
Induced polyploidy, and the addition or removal of chromosomes using a technique called chromosome engineering may also be used. Agricultural research on potato plants. When a desirable trait has been bred into a species, a number of crosses to the favored parent are made to make the new plant as similar to the favored parent as possible.
