- Which of the following is a form of a heritable trait that enhances an individual’s fitness? Adaptation Lineage FitnessWhich of the following BEST describes the relationship between genotype, phenotype, traits, and the environment? O Organisms acquire traits during their lifetime that alter their phenotype. This allows individuals to better adapt to their surroundings, and to pass on their phenotypes to their offspring regardless of their genes. An organism's phenotype is largely determined by its genes, or genotype. The relationship between an organism's phenotype and its environment determines the frequency of traits in a population. O The relationship between an organism's environment and its genotype determines the type of phenotype it will develop. Phenotypes are largely determined by the environment and organisms display traits that are unrelated to their genes.Which of the following is NOT a characteristic of determining whether a feature is an adaptation? Group of answer choices Reliability Genetic significance Efficiency Economy
- Which of the following would be the best measure of an organism’s evolutionary fitness? Lifespan Number of offspring Number of siblings Physical strengthWhich of the following are arguments against the expression "survival of the fittest"? Choose all that apply. (1, 2, 3, or 4 could be correct) "Fittest" implies absolute fitness, when relative fitness of one genotype compared to others is more important "Fittest" makes it sound like it is about physical fitness, when whether an individual reproduces may depend on other traits "Fittest" makes it sound like an individual will be fit in all environments, when in reality the same genotype may have different fitness in different environments Reproduction is more important than survival for transmitting genetic differences to progenyWhich of the following best differentiates between genotype and phenotype? Genotype is an organism's genetic makeup, and phenotype is the observable traits of an organism Genotype is the observable traits of an organism, and phenotype is an organism's genetic makeup Genotype and phenotype both refer to an organism's genetic makeup Genotype and phenotype both refer to the observable traits of an organism
- What is fitness? To what degree does fitness dependon the environment in which organisms live?Evolutionary fitness refers to? the contribution an individual makes to the gene pool of the next generation the ability of an organism to survive in a particular environment Othe ability of an organism to adapt to changing environmental conditionsHow is variation different from adaptation? * No answer Variation is always caused by mutation while adaptation is a heritable trait. Variation is a difference within an individual organism from the rest of the population. An adaptation is a feature that helps an organism survive in its environment. Adaptation is a difference within an individual organism from the rest of the population. A variation is a feature that helps an organism survive in its environment. Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations.
- Which of the following definitions best describes 'biological fitness'? O a heritable trait that increases the match of an individual to its environment. competition among individuals for resources that allow them to have more offspring. O variability in the population for a trait that increases survival. the ability of an individual to produce offspring that survive and reproduce, relative to other individuals in the population. similar reproductive success among individuals in a population.Phenotypic plasticity is the ability of an individual organism to express two or more genetically controlled phenotypes in response to environmental variation. Give an example and give some reasons why organisms depend on phenotypic plasticity instead of maintaining all their systems in a maximum sate of readiness at all times.Which of the following statements about the theories of senescence is correct? Question 2 options: The reason why organisms become old and decrepit is because an individual would often have accumulated too much energy in its lifetime in the form of fat reserve; therefore, an older individual often dies from old-age related diseases. An allele that shows its deleterious effect later in life will always have a smaller impact on an organism's fitness than an allele that shows its deleterious effect early in life. Therefore, late-acting deleterious mutations can be fixed in the population, resulting in shortened lifespans. The allele that can result in early reproduction will always be selected for, even if it comes with a cost of earlier senescence. Typically, for species that live fast would usually die young. None of the above
