Summary
Genetic recombination rates can change based on environmental and internal factors, offering an evolutionary advantage. Understanding this plasticity is key to explaining the persistence of sexual reproduction.
Area of Science:
- Evolutionary biology
- Genetics
- Molecular biology
Background:
- Meiotic recombination drives genetic variation and adaptation in sexual eukaryotes.
- The influence of varying recombination rates and features on evolution is not well understood.
Purpose of the Study:
- To review the plasticity of meiotic recombination rates in response to various factors.
- To discuss empirical evidence and theoretical models of recombination plasticity.
- To identify research gaps and formulate questions regarding the evolution of recombination.
Main Methods:
- Literature review of empirical studies on recombination rate sensitivity.
- Discussion of theoretical models explaining the evolution and impact of recombination plasticity.
- Analysis of evidence from diploid experiments versus haploid-based theory.
Main Results:
- Recombination rates exhibit plasticity influenced by extrinsic and intrinsic factors.
- Theoretical models suggest plasticity can be evolutionarily advantageous, even with costs.
- A discrepancy exists between diploid experimental evidence and haploid theoretical assumptions.
Conclusions:
- Recombination plasticity may explain the evolutionary persistence of sexual reproduction.
- Further research is needed to bridge the gap between empirical data and theoretical frameworks.
- Understanding conditions favoring recombination plasticity is crucial for evolutionary insights.

6.0K
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.

3.6K
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.

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...

01:30Crossing Over
4.5K
Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...

01:09Mutation, Gene Flow, and Genetic Drift
58.8K
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).

02:13Overview of Transposition and Recombination
15.9K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...
