Genetic Screens02:46

Genetic Screens

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 result in visible changes...
Human Genetics01:28

Human Genetics

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 Designs01:23

Behavioral Genetics and Its Designs

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...

Overview
Genetic Variation01:25

Genetic Variation

Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles, which...
What is Population Genetics?01:25

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.While some alleles of a given gene might be observed commonly, other variants...

Area of Science:

  • Genetics and Public Health
  • Genetic Literacy

Background:

  • Growing genetic knowledge impacts society.
  • Public understanding of genetics is often mediated by media.
  • A gap exists in understanding basic genetic concepts.

Purpose of the Study:

  • To assess general population understanding of "genetics" and "genes."
  • To explore public beliefs about gene location within the human body.

Main Methods:

  • Conducted in-depth, one-on-one telephone interviews with US adults.
  • Asked questions about the understanding and location of genes.

Main Results:

  • Responses varied widely, indicating a broad spectrum of understanding.
  • Many participants expressed hesitation or frustration when defining genetic terms.
  • Some responses revealed a fundamental lack of understanding of basic genetic science.

Conclusions:

  • Conversational familiarity with genetic terms does not equate to scientific understanding.
  • Gaps in genetic literacy may impede effective public health initiatives and healthcare.
  • Further public education is needed to improve genetic literacy across society.
