After filling out the information above, answer this question in depth (at least 5 sentences). Use your notes as necessary. Why may chromosomal disorders be more detrimental than DNA mutations?

Chromosomal disorders are the disorders that are caused due to the presence of extra chromosomes, or absence of one or more chromosomes or specific part of the chromosomes. Mutation can be defined as the change that occurs in the genetic makeup of the organism either during copy of genome during replication or due to external factors like exposure to ultraviolet radiations, cigarette smoke, and due to carcinogenic agents.

Explanation:

The change in shape of the chromosome as compared to the normal one also exert influence over the functions. Down syndrome, Klinefelter syndrome, Turner syndrome, and others are the examples of the chromosomal disorders. These syndromes affect the normal functioning of the human being rendering it unfertile, rudimentary development of sex organs, development of traits in opposite sex, induce short life span, poor health, lack of proper mental development, and other abnormal characteristics in the effected individuals.  On the other hand mutations are not always detrimental, only a small percentage of mutations can cause genetic disorders. Some mutations can change the genetic makeup by does not affect the functioning of the protein thus the physiological functions of the body are remained restored.
