Question

The Y chromosome is the most well-known genetic marker identifying those who are most likely to

a. form stereotypes
b. engage in aggression
c. experience cognitive dissonance
d. commit the fundamental attribution error
e. discriminate against others

Answer 1

The Y chromosome contains the SRY gene which determines male sex in humans. Behavior like aggression is influenced by a combination of genetic factors and environmental conditions, not solely determined by the Y chromosome.

Therefore the correct answer is option is b) engage in aggression

Step-by-step explanation:

The Y chromosome is a genetic marker that determines male sex in humans. Unlike the X chromosome, which has around 2,000 genes, the Y chromosome has fewer than 100 genes. The key function of the Y chromosome is to determine sex through a gene called the SRY gene, which triggers an embryo to develop male characteristics.

While behavior is influenced by genetic factors, it's important to note that the environment plays a significant role in shaping actions such as aggression. For instance, the MAOA gene on the X chromosome has been associated with aggressive behavior, but not every individual with the variant allele exhibits violent tendencies; environmental factors are critical in this context. Thus, identifying those who are most likely to engage in aggression is complex and cannot be attributed to the Y chromosome alone.
