Genetic Screens02:46

Genetic Screens

4.6K
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...

Behavioral Genetics and Its Designs

1.4K
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...

Genome-wide Association Studies-GWAS

12.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Human Genetics

1.9K
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...

Genetic Variation01:25

Genetic Variation

1.6K
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,...

What is Population Genetics?01:25

What is Population Genetics?

53.8K
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.

Area of Science:

  • Social Sciences
  • Genetics
  • Data Science

Background:

  • Social surveys often face data quality challenges, including missing data, reporting errors, and inconsistencies.
  • Traditional data quality control methods have limitations in addressing complex data issues.

Purpose of the Study:

  • To introduce and evaluate a novel approach using genetic data for improving data quality in social surveys.
  • To demonstrate the utility of genetic information in detecting and repairing various data flaws.

Main Methods:

  • Utilized genetic data from two large-scale social surveys: the College Roommate Study (ROOM) and the National Longitudinal Study of Adolescent Health (Add Health).
  • Employed proportion identical by descent (PID) scores to assess genetic relatedness and identify familial relationships.
  • Applied bio-ancestry scores to analyze population origins and resolve racial data discrepancies.
  • Examined sex chromosomal information for cross-checking self-reported sex.

Main Results:

  • Proportion identical by descent scores effectively identified misreported and unreported sibling relationships and detected misrepresented participants.
  • Bio-ancestry scores successfully repaired missing race data and resolved discrepancies in self-reported race measures.
  • Sex chromosomal information provided a means to cross-check self-reported sex accuracy.

Conclusions:

  • Genetic data offers a powerful and innovative tool for enhancing the quality and reliability of social survey data.
  • This initial effort highlights the potential for integrating genetic information into data quality control protocols.
  • Future research can explore broader applications of genetic data for improving social science research integrity.
