Genetic Variation

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...

Evolutionary Relationships through Genome Comparisons

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...

Gene Evolution - Fast or Slow?

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Multi-species Conserved Sequences

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Area of Science:

Population genetics
Human evolutionary studies
Genomic diversity analysis

Background:

Recent advances in genome technology have intensified interest in human genetic diversity.
Understanding genetic variation within and between populations is crucial for addressing questions about race.

Purpose of the Study:

To apply generalized hierarchical modeling to analyze human DNA data sets.
To investigate patterns of genetic diversity in relation to human populations.

Main Methods:

Analysis of two DNA datasets: one with whole-genome resequencing data (32 individuals, 8 populations) and another with short tandem repeat (STR) genotyping data (928 individuals, 46 populations).
Utilized generalized hierarchical modeling to assess genetic diversity patterns.

Main Results:

Significant differences in genetic diversity levels were observed among populations.
A clear pattern of nested subsets in DNA diversity was identified.
Genetic diversity in non-Sub-Saharan African populations is a subset of that found in Sub-Saharan African populations.

Conclusions:

The observed DNA diversity pattern challenges the use of 'race' as a meaningful genetic classification.
The findings suggest that some populations may fit into multiple racial categories, while others may not fit into any.
The current Linnean classification system is inadequate for accommodating these complex genetic patterns.
