Not all traits are determined solely by genes. Many traits have been found to exhibit phenotypic plasticity, which occurs when individuals with the same genotype exhibit different phenotypes in different environments. Which of the following is an example of phenotypic plasticity? a) Well-maintained hedges can be shaped into artistic displays. b) A person who experienced malnutrition as a child is short in stature as an adult. c) Bears living in the arctic developed white fur and cold tolerance over many generations. d) Certain breeds of dog have been bred for specific traits, such as poodles being bred for intelligence.

Researchers think that the animal nervous system evolved through the co-opting of genes with other functions, such as cell-to-cell communication. this is an example of a) novel traits. b) gene recruitment. c) complex adaptions. d) promiscuous proteins. Question 11 (4 points) A behavior can evolve through natural selection if CHOOSE ALL THE TRUE RESPONSES. there is variation in the behavior among individuals in the population. the behavior increases longevity the behavior is heritable

Application/Analysis Which of the following is not required for a behavioral trait to evolve by natural selection? (A) In each individual, the form of the behavior is determined entirely by genes. (B) The behavior varies among individuals. (C) An individual's reproductive success depends in part on how the behavior is performed. (D) Some component of the behavior is genetically inherited.
