Concept explainers
To explain: The term sexual selection.
Introduction: The purpose of reproduction is to transfer the inherited genes to the next generation. The passing of genes from one generation to another generation make the required variations to the progeny. This will help in the better survival of the species. Selection of the desired traits which is responsible for the survival of an organism is considered under this category.
To explain: The factors that influence mate choice.

-  why do females have a greater disadvantage compared to males concerning sexual reproduction? How has this difference between the sex shape sexual selection in general? Choose one form of communication and explain how it is used by competing sex is attracting a mate. arrow_forwardWhat are Mate Preferences Between Women and Men?arrow_forwardThe good genes model of sexual selection is a popular hypothesis for mate choice. What is an underlying flaw with the hypothesis that must be explained?arrow_forward
- What is sexual selection? How is sexual selection similar to and different from other forms of natural selection?arrow_forwardWhat is purposeful control over mating by choice of parents for the next generation?arrow_forwardExplain how sexual selection might lead to a)sexual dimorphism and b) members of one sex (usually male) having traits that do not enhance their survivalarrow_forward
- Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forwardin sexual selection I need an explanation of why one sex is more choosy than the otherarrow_forwardIn the context of the runaway sexual selection hypothesis, what role does female mate choice play in the evolution of exaggerated traits in males? Females ignore males with exaggerated traits in favor of other factors such as resources Females display exaggerated traits themselves to attract males with similar traits Females have no preference for males with exaggerated traits Females actively select mates with these traits, leading to their exaggerated developmentarrow_forward
- Do females select mates basedon traits indicative of “good genes”?arrow_forwardWhich of the following statements about inter- and intra-sexual selection is FALSE? O Males are typically the sex experiencing intrasexual selection because they are generally limited by access to mates, whereas females are generally limited by access to resources. Intersexual selection can explain the occurrence of extravagant display traits in males such as the ornate coloration in guppies. Males competing against each other to aquire the best nuptual gift is an example of intrasexual selection. O Either intersexual or intrasexual selection may occur within a population, but not both.arrow_forwardHow does competition influence natural selection? Is the presence of competitors a selective force?arrow_forward
