Human Genetics

1.4K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Behavioral Genetics and Its Designs

994
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Stereotypes, Prejudice, and Discrimination

94.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Surveys02:16

Surveys

16.6K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Genetic Screens02:46

Genetic Screens

5.6K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Summary

African-Americans in Philadelphia show lower awareness and more concerns regarding predictive genetic testing for cancer risk compared to Caucasians. These disparities may impact future testing uptake.

Area of Science:

  • Genetics
  • Public Health
  • Sociology

Background:

  • Predictive genetic testing offers insights into cancer risk.
  • Understanding racial disparities in awareness and attitudes is crucial for equitable healthcare access.

Purpose of the Study:

  • To investigate differences in attitudes toward predictive genetic testing for cancer risk between African-American and Caucasian residents of Philadelphia.

Main Methods:

  • A cross-sectional survey was conducted among adults awaiting jury duty in Philadelphia.
  • The survey assessed awareness and attitudes regarding predictive genetic testing.

Main Results:

  • Awareness of predictive genetic testing was significantly lower among African-Americans (49%) than Caucasians (72%).
  • African-Americans expressed greater concern about potential government misuse of genetic tests for labeling groups as inferior.
  • African-Americans were less likely to perceive the health benefits of genetic testing, such as aiding healthcare management or disease research.

Conclusions:

  • Significant racial differences exist in Philadelphia regarding awareness and attitudes toward predictive genetic testing for cancer risk.
  • Lower awareness, reduced belief in benefits, and heightened concerns about discrimination among African-Americans may lead to future disparities in testing uptake.
