Is there a specific location for particular chromosomes?
Is there a particular chromosome on which thalassemia is located
What does it mean to say that a gene is linked to a chromosome?
This means that the gene is physically located on that particular chromosome.
Genes which are linked together to produce a particular trait?
They are located on one chromosome.
Why is Autism located in the brain?
Autism isn't located in the brain, autism is a type of brain. Autism is a neurological variation, we don't say that autism is in the brain in the same way that we don't say that African-American is in the skin.
What organ system is autism located in?
Autism mostly has to do with the brain.
What chromosome is autism on?
Yes. There is a link, but this does not mean it causes autism. However, there are some aspects of chromosome 1 that make it of interest in autism research. They do not describe it as causing autism, but instead as an autism susceptibility gene. Links to articles, abstracts, or reviews are in the "Related Links" section below.
What can an extra chromosome do?
Yes, it is possible to have XXX, XXY, or XYY sex chromosomes.
What gene and chromosome is mutated in autism?
Most studies focus on autism or autism spectrum disorders, rather than Asperger's Syndrome specifically. More than one chromosome is linked to autism spectrum disorders. The chromosomes involved according to various studies are listed below. A few sites providing information on the genetics of autism highlight results about several of the chromosomes: Exploring Autism: A Look at the Genetics of Autism Autism is Likely to Be Linked to Several Genes There are also articles that could be available through your library's electronic database subscriptions or available in journal form from an academic library. Some hospitals also subscribe to electronic databases with medical information and allow public access.

Illustration of metacentric chromosome?
A metacentric chromosome is one in which the centromere is located in the center of the chromosome.
What is nondisjunction in chromosomes and what is the result?
Nondisjunction is the addition or deletion of an entire chromosome. The result could be autism or downs syndrome
Will a child have autism if an extra chromosome is on the 21 pair?
no, an extra copy of chromosone 21 causes down syndrome
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
