Competition02:34

Competition

21.4K
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Inclusive Fitness00:57

Inclusive Fitness

23.7K
Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Types of Selection01:46

Types of Selection

37.5K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Impact of Groups on Groups

352
Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

Microbial Interactions: Competition01:26

Microbial Interactions: Competition

94
Microbial competition is an ecological interaction in which microorganisms vie for limited resources within shared environments. These resources may include nutrients, space, or light, depending on the system. The intensity and outcome of competition are influenced by the environmental context, such as nutrient availability, spatial constraints, and the diversity of microbial species present. These competitive interactions significantly influence the structure, function, and resilience of...

Natural Selection and Mating Preferences01:06

Natural Selection and Mating Preferences

881
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
Females, due to their biological roles in conception, pregnancy, and nursing,...

Summary
This summary is machine-generated.

This study models population response to selection considering competition effects. Relative efficiencies of mass, clonal, and full-sib selection depend heavily on the type and magnitude of competition, making predictions impossible without further constraints.

Area of Science:

  • Quantitative Genetics
  • Population Genetics
  • Evolutionary Biology

Background:

  • Understanding population response to selection is crucial in quantitative genetics.
  • Previous models often simplified or omitted complex competition effects.
  • Phenotypic units, including individuals and related groups, are key to selection response.

Purpose of the Study:

  • To formulate a model for the response of randomly mating populations under selection of phenotypic units.
  • To incorporate additive and dominance competition effects into the selection model.
  • To analyze the relative efficiencies of different selection methods under varying competition scenarios.

Main Methods:

  • Developed a three-step derivation for population response.
  • Defined 22 quadratic components for individual, neighbor, and interaction effects.
  • Expressed covariances and variances in terms of these components for different selection types (mass, clonal, full-sib).

Main Results:

  • Quantified individual and neighbor effects, including interactions across loci and alleles.
  • Defined covariances between phenotypes and offspring based on genotype commonality.
  • Showed that selection method efficiency is contingent on unspecified competition parameters.

Conclusions:

  • The relative efficiencies of mass, clonal, and full-sib selection cannot be predicted without defining constraints on competition effects.
  • The magnitude and type of competition are critical factors influencing selection response.
  • Further research is needed to characterize competition to enable predictive models for selection efficiency.
