[Genetics of human behavior: problems, results and prospects]

Area of Science:

• Behavioral genetics
• Human genetics
• Psychometrics

Context:

• Modern behavior genetics faces challenges in understanding human trait inheritance.
• Existing psychometric inventories provide data for genetic analysis.

Purpose:

• To formulate key problems in contemporary human behavior genetics.
• To propose methodologies for studying genetic influences on behavior.
• To investigate the inheritance patterns of personality traits.

Summary:

• Mendelian analysis revealed a major-gene inheritance mode for 20% of scales across the MMPI, 16 PF, and PDI questionnaires.
• This finding suggests significant genetic underpinnings for specific personality dimensions.
• The study outlines avenues for future research in human behavior genetics.

Impact:

• Provides a foundation for understanding the genetic architecture of personality.
• Highlights the utility of Mendelian analysis in behavior genetics.
• Suggests specific personality traits may be strongly influenced by single genes, guiding future research efforts.
