Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism01:21

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

827
Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Gene Duplication and Divergence02:37

Gene Duplication and Divergence

8.2K
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...

Limits to Natural Selection

35.8K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Evolution of New Traits in Microbes

31
Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

65.7K
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).

Convergent Evolution01:54

Convergent Evolution

34.4K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

    Area of Science:

    • Evolutionary Biology
    • Game Theory
    • Population Genetics

    Background:

    • Traditional evolutionary games often simplify population genetics, overlooking diploidy and sexual reproduction.
    • Modeling complex evolutionary dynamics requires incorporating genetic mechanisms like recombination.
    • Existing frameworks may not fully capture the nuances of evolution in sexually reproducing diploid populations.

    Purpose of the Study:

    • To present an analytical framework for polymorphic evolutionary games that explicitly models diploid genetics and sexual reproduction.
    • To adapt traditional evolutionary game theory to diploid populations with sexual recombination.
    • To provide a method for analyzing evolutionary stability in terms of genotypes and phenotypes.

    Main Methods:

    • Developed a framework by integrating diploid genetics and sexual recombination into traditional evolutionary games.
    • Switched from phenotypes to haplotypes as the pure strategies in the game.
    • Calculated strategy payoffs by summing phenotype payoffs weighted by gamete production probabilities.

    Main Results:

    • The resulting game is structurally identical to established evolutionary games with non-linear payoffs.
    • The framework allows analysis using existing analytical tools for such games.
    • Results can be translated to assess genotypic and phenotypic evolutionary stability.

    Conclusions:

    • The proposed framework offers a robust method for studying evolutionary processes in diploid, sexually reproducing populations.
    • It bridges the gap between traditional game theory and complex genetic realities.
    • This approach enhances the understanding of evolutionary stability in a broader biological context.
