What is the cube of 13?
13 cubed = 2,197
How many square feet is a room 13 feet long and 13 feet wide?
Multiply 13 x 13, that comes to 169 square feet.
How many toothpick are in a 13 by 13 square?
12
10 x 13 equals how many square feet?
10 by 13 means 10 times 13. all you do is add the zero from 10 to the 13 and you get 130.
13 feet by 13 feet. how many square yards?
13' x 13' (169 square feet) = 18.77 square yards. (divide square feet by 9 to get square yards)
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
What are four types of chromosomal mutations?
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
What is the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18

What chromosome is affected by Lobstein Syndrome?
13
What number of chromosomes are affected in tourette syndrome?
Either chromosome 13 or 7. Mostly 13
What causes Patau syndrome and how does it differ from Down syndrome?
Patau syndrome is a very rare syndrome caused by a problem in the chromosomes, the structures in the body's cells that contain DNA. The specific chromosomal problem in Patau syndrome is that the cells have three copies of chromosome 13, as opposed to the usual two copies in most people. Because there are three copies of chromosome 13, the condition is also called trisomy 13. The cause of Patau syndrome is similar to Down syndrome. Like Patau syndrome, Down syndrome is caused by having an extra copy of a certain chromosome. Individuals with Down syndrome usually have an extra copy of chromosome 21. Thus, Down syndrome is commonly called trisomy 21. Perhaps not surprisingly, the cause of the trisomy in both Patau and Down syndromes is similar. A phenomenon called nondisjunction is responsible for most cases of trisomy 13 and 21. Nondisjunction is an error that can occur during cell division (specifically the cell division process called meiosis). Rather than splitting evenly, cells that have undergone nondisjunction typically split unevently into two cells; one cell receives one extra copy of a chromosome, while the other is deficient in the chromosome. A major risk factor for nondisjunction is advanced maternal age. The chance of nondisjunction increases significantly once mothers are 35 years old and greater. As you'd expect, the risk of Patau and Down syndromes increases considerably with advanced maternal age.

What are alternative names for Patau syndrome?
Patau's Syndrome Trisomy 13 Syndrome Trisomy D Syndrome Trisomie 13 Trisomee Trisome Trisomic Chromosomal Abnormalities, Chromosome Anomalies, Disorder Fetal Aneuploidy
What is the incidence of patau syndrome?
Patau syndrome, also known as Trisomy 13, is an abnormality of chromosomes in which a patient has an additional 13th chromosome due to a failure of chromosomes to split during meiosis. It can cause the following conditions: motor & mental retardation, extra digits, microcephaly, low-set ears, failure of the forbrain to divide properly, heart defects, eye defects, cleft palate, spinal defects, abnormal genitalia, abnormal palm patterns or overlapping of fingers over thumb.

What diseases are found in chromosomes?
* Down Syndrome -- an extra 21st chromosome* Angelman Syndrome -- an absence of chromosome #15 in the brain* Fragile X Syndrome -- a deficiency in one of the x chromosomes* Rett Syndrome -- deletion of an entire x chromosome (mainly strikes females)* Patau Syndrome -- tripling of chromosome #13 (infants appear mutilated)
If a human gamete with an extra chromosome participated in fertilization with a normal human gamete what condition results?
A trisomy. Trisomies are usually fatal in all chromosome pairs except 5, 13, 21 (these cause Down syndrome), and 23 (The chromosome pair that determines gender)
If a human gamete with an extra chromosome participates in fertilization with a normal gamete what conditions result?
It depends on what's missing. Zygotes missing a chromosome (monosomy) have 45 chromosomes and many do survive; some human monosomies are monosomy 7, 11 or 13. A monosomy X results in Turner syndrome; there must be at least one X chromosome, or the embryo won't survive.
