Many inherited disorders in humans are controlled by a single gene. Achondroplasia is a form of dwarfism. About one out of 25,000 people has achondroplasia. The homozygous dominant genotype causes death of the embryo, and therefore only heterozygotes, individuals with a single copy of the defective allele, have this disorder. This also mean that a person with achondroplasia has a 50% chance of passing the condition on to any children. Achondroplasia is a recessive allele.

What chromosomes are responsible for dwarfism?
Some studies have isolated defects for the production of pituitary hormones to the short arm (the "p" end) of chromosome 3 at a specific location of 3p11. Other studies have found changes on the short arm of chromosome 7.
How is a chromosome effeced by achondroplasia?
The only difference in the chromosome is the presence of the allele that results in an individual with acondroplastic dwarfism. The chromosome affects the structure of the organism, the allele affects the growth plates of the long bones resulting shortened limbs.
Is there a specific location for particular chromosomes?
Chromosomes are typically located within the nucleus of a cell. Each type of chromosome has its specific location within the nucleus, but their organization can vary depending on the stage of the cell cycle and the cell type. Within the nucleus, chromosomes are organized into distinct territories.
A segment of chromosome responsible for a particular characteristic?
DNA or genens these are the segments of the chromosome.
What is the presence of three of a particular chromosome?
The presence of three copies of a particular chromosome is known as trisomy. This genetic condition can lead to developmental abnormalities, such as Down syndrome which is caused by trisomy of chromosome 21.
Which chromosome is dwarfism on?
69 haha just kidding
What does it mean to say that a gene is linked to a chromosome?
When a gene is linked to a chromosome, it means that the gene is physically located on that chromosome. This means that the gene is inherited along with the chromosome it is located on, and may be inherited together with other nearby genes on the same chromosome.

Is achondroplastic dwarfism a gene malfunction or mutation?
it is a mutation of the gene FRG3 in chromosome 4

Are all sex-linked traits located on the X chromosome?
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
What chromosome is Wiskott-Aldrich syndrome on?
It's located on the X chromosome.
Are linked genes genes located on the same chromosome?
Yes, linked genes are genes located on the same chromosome.
What condition is carried on a chromosome other then the sex chromosome?
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
Which chromosome is cri du chat located?
chromosome 7 according to the internet
