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...
Multi-input and Multi-variable systems01:22

Multi-input and Multi-variable systems

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence of...
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...
Incomplete Dominance01:43

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).Mechanisms of Genetic VariationThe original sources of genetic variation are mutations,...
Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

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...

Area of Science:

  • Systems Biology
  • Computational Biology
  • Genomics

Background:

  • Identifying gene interactions is crucial for understanding cellular processes.
  • Current methods often rely on simple statistical correlations, missing complex, cooperative interactions.
  • Higher-order interactions, involving multiple genes, are vital in cellular pathways but difficult to detect.

Purpose of the Study:

  • To define and computationally identify higher-order interactions among genes.
  • To develop methods capable of detecting multivariate statistical dependence in biological networks.
  • To apply these methods to uncover cooperative gene regulation in human B cells.

Main Methods:

  • Utilized maximum entropy techniques to define multivariate statistical dependence.
  • Developed novel computational tests for identifying these higher-order dependencies.
  • Applied the methods to synthetic networks and real microarray data from human B cells.

Main Results:

  • The developed procedure successfully identified dependencies in undersampled regimes, even when joint probability distributions were not reliably estimated.
  • Analysis of human B cell microarray data revealed that third-order statistics, unlike second-order ones, could uncover gene relationships.
  • These identified relationships highlight cooperative gene regulation within cellular pathways.

Conclusions:

  • Higher-order statistics are essential for accurately inferring complex gene interactions in systems biology.
  • The proposed maximum entropy-based approach provides a robust method for detecting cooperative gene regulation.
  • This work advances the ability to map intricate cellular pathways by identifying previously undetectable gene relationships.
