On what chromosomes can you find the genetic disorder called Down Syndrome?

What is the genetic disorder that causes excessive hair growth?

Hypertrichosis very rare disorder also called werewolf syndrome.

What is a punnet square for Down syndrome?

Down Syndrome is not represented by a punnett square because it is not a genetic disorder. Instead, it is a chromosomal disorder. Humans have 23 pairs of chromosomes adding to a total of 46 chromosomes. Individuals who have Down Syndrome have a total of 47 chromosomes because instead of having a set of 2 #21 chromosomes, he/she has 3 #21 chromosomes. This is a result of nondisjunction which can occur during meiosis. During meiosis, the chromosomal number is supposed to be halved. During nondisjunction, all of the homologous chromosomes (matching chromosomes from mom and dad) do not separate during meiosis. In the case of Down Syndrome, the #21 chromosomes fail to separate during meiosis. This results in an egg or sperm cell having one less or one more chromosome #21. If a normal egg or sperm forms a zygote with a egg or sperm that has an extra #21 chromosome, the resulting person will have Down Syndrome, also called Trisomy 21. The same thing can happen for other chromosomes, resulting in a different disorder. This question has been improved by another user: actually, this is both a genetic disorder and a chromosomal disorder. It is a genetic disorder because this disorder is often transmitted from one (or both) of the parents to their young. It is possible to make a punnett square, however there is a better way to do this, which is why you probably will not find a punnett square of this disease online. The better way is by using a karyotype. I know this because i am in a 9th grade bio honors class and i have been studying this disease for over 2 weeks now.. hi yea no your wrong because down syndrome is a genetic disorder :)

What are two diseases linked to the X chromosome?

One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.

What condition occurs when a human zygote has 47 chromosomes?

A human zygote with 47 chromosomes has a condition called trisomy, specifically trisomy 21 if the extra chromosome is chromosome 21. This results in Down syndrome, a genetic disorder characterized by intellectual disability and physical abnormalities.

Which term is defined as all the genes in a person's twenty-three pairs of chromosomes?

Humans without a disorder will have 23 pairs of chromosomes. However, there are many disorders caused by different numbers of chromosomes. For example, Trisomy 21 (Down Syndrome) is a disorder caused by the presence of an extra chromosome 21.

Is down syndrome a disease or a disorder?

Down syndrome is a genetic abnormality and would be called a genetic disorder; however, complications associated with Down syndrome can increase the risk of a number of diseases, such as congenital heart disease. To give another example, cancer is a disease, but in some it may stem from a genetic disorder.

What is fish smell called?

Fish smell is simply called fish odor. If you are thinking of fish odor syndrome, it is called trimethylaminuria, and is a rare genetic disorder.

What happens if they don't properly separate in nondisjunction?

If chromosomes do not properly separate during cell division in a process called nondisjunction, it can lead to gametes with an abnormal number of chromosomes. If such a gamete is involved in fertilization, it can result in genetic disorders like Down syndrome, Turner syndrome, or Klinefelter syndrome, depending on which chromosomes are affected. This can cause developmental and health issues in the resulting offspring due to an imbalance in genetic material.

What is marfansyndrome?

Marfan syndrome (also called Marfan's syndrome) is a genetic disorder of the connective tissue. People with Marfan's tend to be unusually tall, with long limbs and long, thin fingers.

The failure of replicated chromosomes to separate is called?

The failure of replicated chromosomes to separate is called nondisjunction. This can lead to an abnormal number of chromosomes in daughter cells during cell division, which can result in genetic disorders such as Down syndrome.

What happens if a egg cell has 24 chromosomes and is fertilized by a sperm cell containing 23 chromosomes.?

The resulting zygote would have 47 chromosomes, which is an extra chromosome compared to the normal human chromosomal number of 46. This condition is called trisomy and can lead to genetic disorders such as Down syndrome.

Does fetal alcohol syndrome lead to Down syndrome?

No, but consuming alcohol during pregnancy can lead to impaired mental development in a condition called Fetal Alcohol Syndrome.
