3. The fixation or rise of prevalence of an allele in a population
4. Argued sexual selection was non-aesthetic, and that females choose traits due to their correlation with male health
6. bias The theory that preference for a given trait existed prior to the evolution of a sexual characteristic.
8. Choice Preferences individuals have for certain traits in potential mates.
10. Hypothesis This hypothesis suggests that males evolve traits that exploit pre-existing sensory biases in females.
11. Argued sexual selection was aesthetic
13. Norm Distribution of phenotypes for one genotype over a range of environmental conditions
14. A sexual characteristic that didn’t evolve for functional purposes

1. Selection Removal of deleterious alleles, keeping the status quo
2. Models Propose that male sexually selected traits evolve due to pre-existing preferences in the perceptual or cognitive systems of females, which originally developed for functions unrelated to mating.
3. Bias A predisposition in an organism's sensory system that makes certain stimuli more attractive or noticeable, often due to ecological or evolutionary factors unrelated to mating.
5. Landscape a 3D representation of fitness as a function of genotype or phenotype
7. Change in DNA/RNA sequence
8. Sexual Selection A type of natural selection that favors traits increasing an individual's chances of reproductive success.
9. The null model of sexual selection
12. Evaluation Cognitive comparison of a signal to an innate template or other received signals
