People with Down syndrome, including Alzheimer's disease and 

epilepsy, have a greater chance of certain diseases. 

Low muscle tone, short stature, a flat nasal 

bridge, and a protruding tongue are some features. 

Down Syndrome arises due to a defect in cell division and affects the body because 

the developmental changes and physical changes of Down syndrome are caused by this extra genetic material.

Common symptoms are:

• Flattened face 

• Small head

•Short neck

•  Protruding tongue

•Poor muscle tone

•Unusually shaped or small ears

•Upward slanting eyelids 

•Short height 

Short and small hand and feet 


A person with Down Syndrome will have intellectual or developmental problems which could be mild, moderate or severe.

Common symptoms are:

• Small head

•Short neck

•  Protruding tongue

•Poor muscle tone

•Unusually shaped or small ears

•Upward slanting eyelids

The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. Examples include silent point mutations.

No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene. 

Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Example : ACTN3 and the super-sprinter variant , hDEC2 and the super-sleeper mutation.
