Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

6.6K
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...

Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

6.4K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Exon Recombination02:32

Exon Recombination

3.9K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon...

What is Population Genetics?

63.3K
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.

Gene Conversion

10.3K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Synteny and Evolution02:31

Synteny and Evolution

3.5K
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...

Area of Science:

  • Genetics
  • Population Genetics
  • Genomic Research

Background:

  • High-resolution recombination maps are crucial for understanding genetic diversity.
  • Existing maps primarily focus on European populations, leaving African populations underrepresented.
  • Significant genetic divergence within Africa suggests a potentially distinct recombination landscape.

Purpose of the Study:

  • To review and evaluate recombination inference methods for African populations.
  • To highlight the challenges and opportunities in mapping African recombination landscapes.
  • To provide guidance on selecting appropriate methods for genetic research in these populations.

Main Methods:

  • Review of existing recombination inference methodologies.
  • Analysis of method strengths and weaknesses for African population data.
  • Development of a decision tree for method selection.

Main Results:

  • Identification of limitations and opportunities for recombination mapping in African populations.
  • Comparative assessment of various recombination inference techniques.
  • Recommendations for optimal methodology tailored to specific research needs.

Conclusions:

  • Accurate recombination maps are essential for African populations.
  • Methodological choices significantly impact downstream genetic analyses.
  • Improved recombination mapping will enhance local ancestry inference, haplotype phasing, and GWAS fine-mapping in African ancestries.
