Summary
The evolution of sex and recombination remains a puzzle. Recent models incorporating realistic factors like finite populations and genome-wide selection better explain how sex and recombination can persist.
Area of Science:
- Evolutionary biology
- Theoretical biology
Background:
- The persistence of sexual reproduction and genetic recombination is a long-standing enigma in evolutionary theory.
- Traditional models often restrict the conditions under which sex and recombination can evolve.
Purpose of the Study:
- To review major models and evidence for the evolution of sex and recombination.
- To highlight recent theoretical approaches that expand the parameter range for their evolution.
Main Methods:
- Review of existing theoretical models in evolutionary biology.
- Analysis of recent research incorporating more realistic assumptions.
Main Results:
- Most models show sex and recombination evolve only under limited parameters.
- Recent approaches with finite populations, long-genome selection, and recombination plasticity broaden evolutionary explanations.
Conclusions:
- Realistic assumptions are crucial for understanding the evolution of sex and recombination.
- The study clarifies similarities and differences between the evolutionary drivers of sex and recombination.

Conservative Site-specific Recombination and Phase Variation
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.

Gene Conversion
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...

Crossing Over
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, duplicated...
Crossing Over
Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process called synapsis.

Exon Recombination
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.
