Topic: Karyotype

	Karyotyping Activity
		This exercise is a simulation of human karyotyping using digital images of chromosomes from actual human genetic studies.
		A karyotype analysis usually involves blocking cells in mitosis and staining the condensed chromosomes with Giemsa dye.
		Karyotyping is one of many techniques that allow us to look for several thousand possible genetic diseases in humans.

	Karyotype - Wikipedia, the free encyclopedia
		Karyotypes are examined in searches for chromosomal aberrations, and may be used to determine other macroscopically visible aspects of an individual's genotype, such as sex (XX vs. XY pair).
		In the "classic" (depicted) karyotype, a dye, often Giemsa, is used to stain bands on the chromosomes.
		Spectral karyotyping is a molecular cytogenetic technique used to simultaneously visualize all the pairs of chromosomes (23 in humans) in different colors.

	Karyotype: Encyclopedia of Genetic Disorders
		Karyotype either refers to the actual composition of the chromosomes in a body cell of an individual or species, or to the actual diagram or photograph of those chromosomes, arranged in their pairs.
		In the construction of the karyotype, the chromosomes are numbered 1 to 22 from longest to shortest.
		The typical female karyotype is written as 46,XX and the typical male karyotype is written as 46,XY.

	Making a Karyotype
		A karyotype is an organized profile of a person's chromosomes.
		In a karyotype, chromosomes are arranged and numbered by size, from largest to smallest.
		To make a karyotype, scientists take a picture of someone's chromosomes, cut them out and match them up using size, banding pattern and centromere position as guides.

	Karyotype Lab (Site not responding. Last check: )
		Karyotyping is the process by which doctors and geneticists take pictures of the chromosomes while the cell are undergoing mitosis.
		Be sure to include the type of abnormality, the total number of chromosomes in the karyotype, the specific chromosome involved, the gender of karyotype, and the reason for the gender.
		The hardcopy karyotypes were generated from a lab manual copy of a basic karyotype by cutting and pasting.

	CyDAS: Class Karyotype
		When a composite karyotype was calculated from single karyotypes with the combine function, it is automatically marked composite.
		If the ploidy level is not given explicitly in the karyotype formula, it is calculated by dividing the arithmetic medium value of chromosome count by the number of chromosomes per haploid set (23 for humans) and rounding to the nearest full number.
		Returns the first aberration in the karyotype whose breakpoints (or in case of derivative chromosomes: whose aberration descriptions) are missing.

	CancerQuest : Cell Division : The Cell Cycle
		The depiction of all of the chromosomes in this manner is known as a karyotype.
		Karyotypes are often performed on fetal tissues during pregnancy to detect chromosomal abnormalities in the unborn child.
		The karyotype shown below is from a male and contains one X and one (much smaller) Y chromosome.

	A Trisomy 18 Journey - Edward's Syndrome Karyotype
		It is often suspected from ultrasound or characteristics seen at birth, but it is diagnosed using a karyotype.
		The 47,XX,+18 indicates that there are 47 chromosomes (normal is 46), that it is a girl (Edward's Syndrome affects girls three times as often as boys), and that the extra chromosome is number 18.
		Karyotype results are usually reported by saying how many cells were tested and how many found the additional chromosome.

	JIS: Tschinkel 2.12.2002
		The basic karyotype is complemented by a description of C- and G-banding patterns.
		The C-banding pattern in spermatogonial metaphase was characterized by the presence of paracentromeric C-bands in all chromosomes, and a distal C-band in chromosome 5.
		The karyotype obtained after staining the chromosomes for G-bands is shown on Figure 4.

	Karyotype - Susan's Place Transgender Wiki
		We stand at the crossroads of gender balanced on the sharp edge of a knife.
		However, some individuals have other karyotypes with added or missing sex chromosomes, including 47,XYY, 47,XXY, 47,XXX and 45,X. The other possibility, 45,Y, does not occur, as an embryo with only a Y chromosome is incapable of survival.
		In the "classic" (depicted) karyotype, a dye, often Giemsa, is used to make bands on the chromosomes visible.

	Introduction to Chromosomes Chromosome Deletion Outreach, Inc. (Site not responding. Last check: )
		When a karyotype is made (see below) the q arm is always put on the bottom and the p on the top.
		The arms are separated by a region known as the centromere (red in picture), which is a pinched area of the chromosome.
		A karyotype is an actual photograph of the chromosomes from one cell.

	Karyotype, Extended Banding, Fluorescent In Situ Hybridization (FISH) - My Child Has - Children's Hospital Boston
		A picture (an actual photograph from one cell) of all 46 chromosomes, in their pairs, is called a "karyotype".
		A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
		The standard analysis of the chromosomal material evaluates both the number and structure of the chromosomes, with an accuracy of over 99.9 percent.

	XYY -- Stereotype of the Karyotype
		Most males have the 46-XY karyotype, but about 1 guy in 1000 has two Y chromosomes, and is an XYY ("diplo-Y", "diplo Y", "YY", "polysomy Y", "Jacob's syndrome").
		The parents were very likely told at the time of karyotyping that their sons had "criminal genes" or something.
		Good study from Finland, where karyotyping is evidently common enough to have allowed a group of dentists to determine that XYY's have notably longer roots on their teeth.

	Karyotype Test
		Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells.
		Determine whether a chromosome defect is present in a fetus.
		Karyotyping also may be done to determine whether chromosomal problems may have caused a fetus to be stillborn.

	Karyotype
		A karyotype illustrates the chromosomal makeup of a cell in an individual or species including the number and arrangement and size and structure of the chromosomes.
		It is a visualization of all of an organism's chromosomes together, each labeled with a different color.
		A karyotype is the cell's entire chromosome complement, and is useful in reliably identifying chromosome variations.

	Karyotyping Activity
		Place this chromosome in the partially completed karyotype below by clicking on its homologous chromosome.
		If you match the chromosome correctly, you will proceed to the next chromosome.
		If you match incorrectly, a page will explain why the chromosome you chose is not the unknown's pair and you can choose again.

	Genetics - Karyotype Identification
		Brief Summary: Students are put into groups and each is given an unknown picture of chromosomes from an individual.
		The students are asked to lake a karyotype from their chromosomes and diagnose the genetic problem (if there is one).
		Student Objective(s): To play a role: each group symbolizes the lab person who gets the chromosomes from a real person with the purpose of diagnosing a genetic condition.
