Karyotypes are arranged with the short arm of the chromosome on top, and the long arm on the bottom. Some karyotypes will designate the short and long arms as p and q, respectively.

Karyotype
Karyogram of human female
A karyotype is the complete set of all chromosomes of a cell of any living organism. The chromosomes are arranged and displayed (often on a photo) in a standard format: in pairs, ordered by size.

Karyotypes can be used to determine if there is an abnormality in chromosome number or structure.

Male intersexuals (karyotype 46XY) (also called male pseudohermaphrodites) have normal testes with female or ambiguous genitalia. They most often result from several different genetic alterations in pathways of testosterone synthesis and metabolism.

An arrayed set of banded chromosomes is called a karyotype and can be used to screen for chromosome rearrangements.
G-, Q-, and R- bandings are not observed with plant chromosomes.

X and Y chromosomes in organisms that determine the sex of an individual. In human beings females have two X chromosomes in diploid cells; males have an X and a Y chromosome. The sex chromosomes comprise the 23rd chromosome pair in a human karyotype.

They also found statistically significant premating isolation between the WH population and the field populations. Finally, the Woods Hole population showed slightly different karyotypes from the field populations.
