Incomplete Dominance01:43

Incomplete Dominance

30.8K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Mate Choice01:20

Mate Choice

11.9K
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.3K
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.

Testing a Claim about Population Proportion

4.0K
A complete procedure for testing a claim about a population proportion is provided here.
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Law of Segregation

When crossing pea plants, Mendel noticed that one of the parental traits would sometimes disappear in the first generation of offspring, called the F1 generation, and could reappear in the next generation (F2). He concluded that one of the traits must be dominant over the other, thereby causing masking of one trait in the F1 generation. When he crossed the F1 plants, he found that 75% of the offspring in the F2 generation had the dominant phenotype, while 25% had the recessive phenotype.

Summary

Wild radish petal color affects mating patterns. Yellow flowers attract more pollinators, leading to higher paternity success for the yellow morph, demonstrating a male-fitness advantage in this plant polymorphism.

Area of Science:

  • Plant biology
  • Evolutionary ecology
  • Population genetics

Background:

  • Floral color polymorphism is common in wild radish (Raphanus raphanistrum).
  • Petal color is controlled by a single genetic locus, with white dominant to yellow.
  • Understanding how this polymorphism affects mating patterns is crucial for evolutionary studies.

Purpose of the Study:

  • To investigate the influence of petal-color polymorphism on mating patterns in wild radish.
  • To determine if pollinator visitation frequency correlates with paternity success.
  • To assess the role of male-fitness advantage in maintaining floral color variation.

Main Methods:

  • Field experiments with experimental populations of yellow- and white-flowered wild radish.
  • Observation of insect visitor behavior, focusing on pollinator discrimination.
  • Quantification of maternal fecundity and paternity success for each morph.

Main Results:

  • Insect visitors, particularly Pieris rapae, showed a strong preference for yellow flowers over white flowers.
  • The yellow-flowered morph sired approximately 75% of all seeds, significantly higher than expected by chance.
  • Maternal fecundity did not differ between morphs, indicating pollen receipt was not limiting.

Conclusions:

  • The male-fitness advantage of the yellow morph is driven by increased pollen export due to pollinator preference.
  • Floral color polymorphism can be maintained by differential attractiveness to pollinators, influencing reproductive success.
  • No evidence of assortative mating or pollen flow based on petal color was found.
