Biological Factors in Relationships

What role do MHC genes play in the immune system of offspring?

• MHC genes suppress the immune system of offspring by limiting antigen diversity.
• MHC genes have no impact on the immune system of offspring.
• MHC genes enhance the immune system of offspring by providing diverse antigen presentation, improving pathogen recognition.
• MHC genes only affect the physical traits of offspring.

What did Wedekind's study aim to investigate regarding MHC genes?

• The study aimed to explore the role of MHC genes in immune response.
• The study focused on the genetic diversity of MHC genes.
• The study investigated the evolutionary history of MHC genes.
• The study aimed to investigate the influence of MHC genes on mate selection.

What were the findings of Wedekind's study regarding women's preferences?

• Women prefer the scent of older men.
• Women are indifferent to men's scent.
• Women prefer the scent of men with similar MHC genes.
• Women prefer the scent of men with different MHC genes.

What does Dr. Helen Fisher argue about romantic love?

• Romantic love is solely a cultural construct without biological basis.
• Romantic love is a fundamental human drive influenced by biology and evolution.
• Romantic love is a temporary emotional state that has no evolutionary significance.
• Romantic love is primarily driven by social norms and expectations rather than biology.

What was the independent variable in Fisher et al's study?

• The treatment or condition applied to the subjects.
• The number of participants involved.
• The location of the study.
• The age of the subjects.

What is the significance of the ventral tegmental area in the context of romantic attraction?

• It regulates heart rate during romantic encounters.
• It is responsible for visual processing in relationships.
• It controls the production of hormones related to stress.
• The ventral tegmental area is significant in romantic attraction as it activates the brain's reward system, releasing dopamine and enhancing feelings of pleasure and desire.

What are the limitations of using fMRI in studying romantic attraction?

• Limitations of using fMRI in studying romantic attraction include limited temporal resolution, difficulty isolating brain regions, individual variability, artificial environments, and ethical concerns.
• fMRI can accurately measure emotional responses in real-time.
• fMRI provides a complete understanding of romantic relationships.
• fMRI is the only method to study brain activity during romantic attraction.

What are some other factors that influence attraction aside from biological explanations?

• Economic status
• Physical appearance alone
• Social, cultural, and psychological factors.
• Genetic predisposition only

What is the role of oxytocin in forming romantic bonds?

• Oxytocin has no effect on romantic bonds.

• Oxytocin is primarily responsible for regulating stress levels in relationships.

• Oxytocin promotes bonding and trust between partners, enhancing emotional connections.

• Oxytocin only affects physical attraction and not emotional bonds.

What are the implications of genetic compatibility on long-term relationship success?

• Genetic compatibility is only important in short-term relationships.

• Genetic compatibility can influence health outcomes in offspring, which may affect relationship dynamics.

• Long-term relationship success is solely determined by communication skills.

• Genetic compatibility has no relevance to relationship success.
