Summary Introduction
Introduction:
Fitness is not only measured by an individual’s reproductive output but also by the reproductive output that individuals bring about through their seemingly altruistic behaviors toward their close kin. This occurs as a result of kin selection.

- a) Which of the following statements describes domestication? It is the process by which animals are trained to do tricks useful for human needs. It is the process by which wild species have been turned into species with traits that are useful for human needs. It is the process by which animals build nests to attract mates and raise young. It is the process by which plants have evolved to fill in ecological niches over time. b)To illustrate how common corn is in a typical American diet, the film narrator gives many examples, from corn-on-the-cob to foods that contain cornstarch and corn syrup.

- The continued evolutionary exaggeration, across generations, of a sexual display trait (e.g., a trait used by males in attracting mates, like the peacock's tail) is most likely due to: a) stabilizing fecundity selection O b) directional sexual selection c) genetic drift d) heterozygote advantage e) directional viability selectionarrow_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_forward6.) What is adaptation? It is a physical or behavioral characteristic that helps _ a.) plant and animals to reproduce b.) a plant grows. c.) a living thing walk d.) a living thing survive. 7.) Which of the following causes a decreasing wildlife population in most of the places in our country? a.) Loss of natural disturbances b.) Loss of carrying capacity c.) Loss of limiting factor d.) Loss of habitat 8.) Cocolisap infestation outbreak has been declared in some parts of the Philippines. The cocolisap feeds on the sap of the coconut tree and injects toxic enzymes, resulting in discolored leaves and deformed plant tissues that retard its growth of coconut tree. This, results in a decrease of the survival rate of coconut trees. Which of the following factors limits the population of coconut trees? a.) Diseases and parasites b.) Competition for resources c.) Emigration d.) Predation 9.) If the number of births in a population is the same as the number of deaths in a…arrow_forward
- What is inbreeding depression and why is it particularly a concern for conservation biology? A) It is a chemical imbalance in the brain of animals forced into close quarters, such as those rescued from the wild and placed in zoos. B) It is a situation where the frequency of an allele over time depends greatly upon its initial frequency, as such if populations are too small, the present alleles are at risk of being lost. C) It is a situation where offspring of genetic relatives have increased fitness, this occurs when populations of animals are large and they mate freely. D) It is a situation where offspring of genetic relatives have reduced fitness, this occurs when populations of animals become too small and they are thus likely to mate with closely related individuals.arrow_forward47) Which statement illustrates the connection between natural selection and overreproduction of a population? A) Populations vary in their inherited traits. B) Species produce more offspring than can survive in the environment. C) Individuals with inherited traits that promote survival tend to have more surviving offspring. D) Individuals with traits that do not enhance survival cannot reproduce.arrow_forward1.) The process in which the genetic composition of a population changes with time is known as evolution. Which of the following mechanisms is not an agent of evolutionary change? A) natural selection B) mutation C) genetic drift D) random mating 2.) Which statement below is not consistent with a population in Hardy-Weinberg equilibrium? A) Genetic drift is occuring B) Random mating is occuring. C) Population size is large. D) Migration is not occuring.arrow_forward
- Biologists sometimes say that “natural selection depends on the specific environment where a species lives.” What does this statement mean? A) A) If populations of a species are in different environments, traits that individuals need to meet their needs in each environment will appear. B) Traits can be helpful or harmful. If populations of a species are in different environments, some traits that are helpful in one environment might be harmful in another environment. C) Traits are always either helpful or harmful, and the environment of a population doesn’t matter. If populations of a species are in different environments, the same traits will always be helpful. D) Species were formed to perfectly match their environment. The traits of individuals in a species depend on the specific environment in which they were created.arrow_forwardSuppose a population of mice is subject to a few years of very cold, dry winters that drastically decreases their numbers. Which of the following factors has affected this population? a) Non-random mating b) Genetic drift c) Migration d) Mutationarrow_forward4.
