Mutations are positive occasionally, beneficial occasionally and omission of information.
Answer: Options 1, 3 and 4.
<u>Explanation:</u>
Mutations are more or less permanent changes. These changes are heritable in the phenotype of an individual. These changes occur because of the alteration in the number, kind or the sequence of nucleotide of the genetic material which is DNA in most of the cases.
Mutations occur at some times in the life of people and they are present in only some cells of the human body. They are not present in all the cells of the human body. These changes can also occur because of environmental factors like ultraviolet radiation from the sun.
In addition the oxygen in the Earth's atmosphere absorbs wavelengths at the edge of the ultra-violet region of the spectrum. The resulting color, which appears like a pale blue, actually is a mixture of all the scattered colors, mainly blue and green.
