A karyotype can be valuable in pinpointing cases of unusual chromosome numbers in a cell.

What unusual result suggested that the eye-color trait is located on the X chromosome?

The unusual result was that in a family, all males had the same eye color as their mothers. This suggested that the gene for eye color is linked to the X chromosome because males inherit their X chromosome from their mothers.


Do women or men have a smaller sex chromosome?

Women have two XX chromosomes, while men generally have XY (barring unusual chromosomal genotypes). The Y chromosome is smaller than the X.


What is unusual about the latitude and longitude of sydney?

Taken together, that pair of numbers is unusual because no other city ...in fact no other point on Earth ... has the same latitude and longitude.


Why are there not isotopes with unusual numbers of protons?

If the number of protons changes so does the element, as the number of protons defines the element.


What happens if a baby has 2 x chromosomes and a y chromosome?

In humans, it is the presence of the Y chromosome that makes an individual a male (not the ratio of X to Y). A normal male will have the sex chromosomes XY. It is possible for males to have either an extra X chromosome, XXY, or an extra Y chromosome, XYY. These are both a type of aneuploidy - an unusual number of chromosomes. XYY males are not very different from XY ("normal") males. They have normal testosterone levels, normal intelligence and normal fertility. They are on average taller than XY males. XYY usually results from an error when sperm cells are formed, which results in a sperm cell that contains 2 Y chromosomes. This combines with the female gamete, which carries an X chromosome - resulting in an XYY individual.

What graph is used for tables of numbers?

The answer depends on the nature of the numbers in the table and what you wish to show in the graph. You can graph virtually any set of numbers. For rather an unusual use of graphics see the attached link:

This human karyotype is unusual because chromosome set?

This human karyotype is unusual because it displays an abnormal number of chromosomes, which can result from genetic disorders or mutations during cell division. Having an unusual number of chromosomes can lead to developmental abnormalities and health problems. Further genetic testing and analysis would be needed to understand the specific genetic condition causing the abnormal karyotype.


Why is huntingtons deisease so unusual?

Huntington's disease is the result of a genetic defect on chromosome 4. This defect causes an excessive repetition of a section of the DNA on this chromosome. A unique characteristic of this disease is that as this gene gets passed down from generation to generation, the number of repeats of this DNA section increases. The more repeats that occur, the greater the chances of the carrier to develop symptoms of the disease at a younger age.
