an error in meiotic cell division
Additional chromosome
The most common condition associated with a deletion of the end of chromosome 5 is: cri-du-chat syndrome.
Down syndrome is a polyploidy (three chromosome 21s)and is considered to be a somatic disorder. The other three are genetic because they are present in the form of a defective allele on achromosome.
Angelman's syndrome is a genetic disorder caused by deletion on genes on chromosome 15 contributed by the mother to child, once you are born with it, the faulty gene has already done the damage. There is no cure for it. Note: If their deletion of the same gene on chromosome 15 contributed by the father, it results in Prader Willi syndrome.
PKU is described as an inherited, autosomal recessive disorder.
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
No, Down's syndrome is only a human genetic disorder. Those with the disorder have an extra chromosome. Raccoons do not get this particular genetic disorder.
Deletion Syndrome or Williams Syndrome
Additional chromosome
A genetic disorder caused by the presence of all or part of a third copy of chromosome 21.
Angelman syndrome is a genetic disorder, as is Down syndrome. But they are not the same. Angelman Syndrome involves a deletion of Chromosome 15, whereas people with Down syndrome have an extra copy of Chromosome 21.
A genetic disorder resulted in seven missing or unexpressed genes on chromosome 15
The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.
It is a type of genetic disorder in which females are affected. This happens when they dont have an X chromosome as in the sex chromosome so the resultant will be XO.
