Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
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...
Synteny and Evolution02:31

Synteny and Evolution

John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral chromosome underwent...
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...
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...

    Resumen

    La variación genética en Asia se correlaciona fuertemente con el idioma y la geografía. El sudeste asiático fue una fuente primaria para las poblaciones de Asia oriental, mostrando un gradiente de diversidad norte-sur.

    Área de la Ciencia:

    • Genética de la población humana Genética de la población humana
    • La genómica es la genómica.
    • Antropología Antropología de la Antropología.

    Sus antecedentes:

    • La vasta diversidad genética de Asia es poco conocida.
    • Los estudios anteriores carecían de un muestreo geográfico completo.

    Objetivo del estudio:

    • Para investigar la estructura geográfica de la variación genética en las poblaciones asiáticas.
    • Explorar la relación entre la ascendencia genética, la geografía y las afiliaciones lingüísticas.

    Principales métodos:

    • Estudio a gran escala de la variación genética autosómica.
    • Análisis de amplias muestras geográficas de poblaciones humanas asiáticas.
    • Análisis del haplotipo para rastrear los orígenes de la población y el flujo genético.

    Principales resultados:

    • La ascendencia genética está fuertemente correlacionada con los grupos lingüísticos y la ubicación geográfica.
    • La mayoría de las poblaciones asiáticas exhiben parentesco genético dentro de sus grupos étnicos / lingüísticos.
    • Más del 90% de los haplotipos de Asia Oriental (EA) se encuentran en las poblaciones del sudeste asiático (SEA) o del centro-sur de Asia (CSA).
    • La diversidad de haplotipos en el este de Asia muestra una estructura clinal, disminuyendo de sur a norte.
    • El 50% de los haplotipos de EA se encontraron exclusivamente en SEA y el 5% en CSA, lo que sugiere que SEA es una fuente ancestral importante para las poblaciones de EA.

    Conclusiones:

    • El sudeste asiático jugó un papel importante como fuente geográfica para las poblaciones del este asiático.
    • La variación genética en Asia está estructurada tanto por la geografía como por la historia lingüística.
    • A pesar del flujo genético, los patrones genéticos distintos reflejan las diversas poblaciones de Asia.
