359686200 | Sexual Selection | A form of natural selection in which individuals with certain inherited characteristics are more likely than other individuals to obtain mates. | |
359686201 | Intrasexual Selection | A direct competition among individuals of one sex (usually the males in vertebrates) for mates of the opposite sex. | |
359686202 | Intersexual Selection | Selection whereby individuals of one sex (usually females) are choosy in selecting their mates from individuals of the other sex; also called mate choice. | |

359686206 | Handicap Hypothesis | females can assess quality of a male by his ability to survive, despite potentially harmful traits --> females invest more in offspring than males | |
359686207 | Sensory Exploitation | A theory of sexual selection that posits that females may initially prefer male traits that elicit the greatest amount of stimulation from their sensory systems. | |
