The role of nurturing in determining one’s behavioral traits has been hotly contested. Historically, geneticists believed that behavioral traits are inherited. After all, many properties of the brain are genetically organized and don't depend on information coming in from the senses. Since active genes are essentially inherited, most traditional geneticists believe that nurturing environment plays little role in shaping one’s behavioral traits.


However, a new line of research indicated that methyl groups can activate dormant genes, bringing about a slew of changes much later in a person’s life. The methyl group works like a placeholder in a cookbook, attaching to the DNA within each cell to select only those recipes - er, genes - necessary for that particular cell’s proteins, telling the DNA what kind of cells to form.  The first such observation was in which methyl groups activated by causes ranging from exposure to certain chemicals to changes in diet set off a cascade of cellular changes resulting in cancer. Because methyl groups are attached to the genes, residing beside but separate from the double-helix DNA code, their study is dubbed epigenetics - “epi” referring to Greek for outer or above. 


Behavioral geneticists, encouraged by this discovery proved that traumatic experiences such as child neglect, drug abuse, or other severe stresses also set off epigenetic changes to the DNA inside the neurons of a person’s brain, permanently altering behavior.  Similarly, through multivariate analysis, they proved that identical twins, in scenarios where one twin has gone through a life altering event, can have vastly different reaction to a stressful situation.


Why does the author state “After all, many properties of the brain are genetically organized, and don't depend on information coming in from the senses”:

  • a)
    to provide a reason for geneticists belief that behavioral traits are inherited.

  • b)
    to prove that active genes and not dormant genes define key behavioral traits.

  • c)
    to describe the role played by genetic inheritance in determining one’s personality.

  • d)
    to indicate that there have been few experiments in the past linking behavior and life experience.

  • e)
    to lay the foundation for the development of epigenetics.

Correct answer is option 'A'. Can you explain this answer?

Answer Choices
A
to provide a reason for geneticists belief that behavioral traits are inherited.
CORRECT: This is what we deduced from our pre-thinking.
B
to prove that active genes and not dormant genes define key behavioral traits.
OUT OF SCOPE: This is not the reason why he states this sentence.
C
to describe the role played by genetic inheritance in determining one’s personality.
OUT OF SCOPE: This sentence does not describe but rather presents a reason.
D
to indicate that there have been few experiments in the past linking behavior and life experience.
OUT OF SCOPE: This is certainly not the reason.
E
to lay the foundation for the development of epigenetics.
OUT OF SCOPE: This is just opposite in connection to epigenetics.
