Chromosome 21.
DOWNS Syndrome.
The most common deffect that will occur with there is nondisjunction on the 21st chromosome is downs syndrome. Downs syndrome is a mental illness that can cause some physical abnormalities such as a large forhead, but also some intellectual delays.
The most common condition associated with a deletion of the end of chromosome 5 is: cri-du-chat syndrome.
At the beginning of cell division, DNA and the proteins associated with the DNA coil into a structure called a chromosome. Chromosomes are visible under a microscope and contain the genetic material (DNA) of an organism.
Periventricular heterotopia is associated with abnormalities of the filamin1 gene on the X chromosome.

downs syndrome is a a chromosome abnormality in which their is an extra copy of the 21st chromosome causing the person to have a flatter face slanted eyes and a mental handicap.
Yes, animals have chromosome 21. It may vary in size or gene content depending on the species. In humans, chromosome 21 is associated with conditions such as Down syndrome.
Translocation Down syndrome is a genetic condition caused by the presence of an extra chromosome 21 due to a rearrangement of genetic material between chromosomes. Unlike the more common forms of Down syndrome, which result from an extra full chromosome 21, translocation Down syndrome occurs when a portion of chromosome 21 becomes attached to another chromosome. This can happen during the formation of reproductive cells or in early fetal development. Individuals with translocation Down syndrome typically exhibit the same physical and cognitive characteristics associated with Down syndrome.
Genetic defects can be associated with autosome and chromosome abnormalities.
The human genes associated with color vision are located on the X chromosome. Specifically, the genes for three types of color receptors (cones) - blue, green, and red - are located on the X chromosome. This is why color blindness, which is more common in men, is often linked to mutations in these genes due to their presence on the X chromosome.
