Frequency-dependent Selection01:21

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...
Understanding Species and Reproductive Barriers01:17

Understanding Species and Reproductive Barriers

A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar and share common characteristics due to their highly similar genomes. However, not all organisms that look alike are members of the same species. Various mechanisms keep most species discrete. While some mechanisms prevent reproductive behavior and fertilization (pre-zygotic isolation), others prevent the production of fertile offspring after mating has...
In- and Out-Groups01:31

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.
Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance01:14

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the anxiety of...
Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
Self-Discrepancy Theory02:45

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Summary
This summary is machine-generated.

Flowering plants use self-incompatibility to prevent self-fertilization. Recent research combines molecular and evolutionary methods to understand the genetic mechanisms and protein interactions involved in these systems.

Area of Science:

  • Plant reproductive biology
  • Molecular genetics
  • Evolutionary biology

Background:

  • Self-incompatibility (SI) is a genetic mechanism in flowering plants preventing self-fertilization.
  • Diverse SI systems exist across plant species, posing challenges for unified understanding.

Purpose of the Study:

  • To review progress in understanding the molecular genetics of self-incompatibility.
  • To explore the nature of recognition proteins and gene separation in SI systems.
  • To investigate the role of suppressed recombination in SI regions.

Main Methods:

  • Combined molecular and evolutionary approaches.
  • Analysis of protein-encoding genes in SI systems.
  • Examination of chromosomal regions associated with suppressed recombination.

Main Results:

  • Recent advances have clarified the molecular basis of SI in various species.
  • Evidence suggests distinct genes for pollen and pistil recognition proteins in some SI systems.
  • SI systems may involve chromosomal regions with reduced recombination.

Conclusions:

  • Understanding SI requires integrating molecular and evolutionary perspectives.
  • The genetic architecture of SI, including gene separation and recombination suppression, is crucial for its function.
  • Further research is needed to fully elucidate the diversity and evolution of SI mechanisms.
