How do changes to genes affect the traits of an organism?

Each distinct gene chiefly controls the production of specific proteins, which in turn affects the traits of the individual. Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits.

Explanation:

This misunderstanding stems from historical precedents. The very first genes were discovered decades ago with quite primitive technology. Thus, the only genes that could be discovered were those with large, dramatic effects on the traits. For instance, a small mutation (change in the sequence of nucleotides) in the gene that codes for RNA that codes for one of the four elements of the hemoglobin protein results in sickle-cell anemia. The red blood cells are, as a result, and the ability of red blood cells to carry sufficient oxygen to the cells is diminished. :) i hope i help

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
