When genes are passed to offspring diseases are also sometimes past to cause genetic disorders. ancestral Disorders are a mutation in a gene. Mutations are changes in the DNA sequence and can happen anytime, from existence a unity cell to being 100 years old.

An abnormal fig of chromosomes is when nondisjunction occurs in the testicle and sperm cell. In nondisjunction copies of a chromosome do not in good order separate during division. When this happens two copies of that particular chromosome are placed in the sex cell.

When and if this cell is used it will come unitedly with one from some other sex cell leaving third copies of this chromosome. Three copies of a chromosome are called trisomy. In most cases trisomy is fatal however on that point are some instances where it is allowed and when this happens a cause defect occurs. bulge out syndrome an d Turners syndrome are typesetters cases of! chromosome abnormalities. Down syndrome is genetic disorder that causes rational retardation, facial nerve disformations, and decreases muscle tone. The disorder happens on the twenty - inaugural chromosome.
