Chromosomal Theory of Inheritance01:39

Chromosomal Theory of Inheritance

56.9K
In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

Overview of Transposition and Recombination

16.3K
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...

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 Evolution

3.4K
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...

Gene Duplication and Divergence02:37

Gene Duplication and Divergence

6.8K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Area of Science:

  • Evolutionary biology
  • Genetics
  • Ornithology

Background:

  • Maintaining local phenotypic variation in highly mobile organisms presents a significant evolutionary puzzle.
  • Understanding the genetic basis of such variation is crucial for conservation and evolutionary studies.

Purpose of the Study:

  • To investigate the genetic underpinnings of phenotypic polymorphism in the common quail (Coturnix coturnix).
  • To explore the role of chromosomal structure in maintaining local adaptation and variation.

Main Methods:

  • Utilized population genomics and cytogenetic analyses.
  • Investigated chromosomal structure and its association with phenotypic traits in common quail.

Main Results:

  • Identified a large chromosomal inversion associated with a specific polymorphism in common quail.
  • The inversion appears to play a key role in maintaining distinct phenotypic variation within the species.

Conclusions:

  • A massive chromosomal inversion is a primary driver of phenotypic polymorphism in common quail.
  • This finding provides a potential mechanism for the maintenance of local adaptation in highly mobile bird species.
