- Say, I have two offspring of my own and also three nephews in Michigan who I have never interacted with at all. Using this as a complete set of my relative (descendants who I share genes with), my actual inlclusive fitness is O 1.75 fitness untis 1.5 fitness units O 1 fitness unit 0.5 fitness unitsWhich 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.Write the survivor rate for AA and Aa genotypes (write the answer in decimal numbers, not in fractions) Survivor rate of AA= Survivor rate of Aa= Write the absolute fitness for AA and Aa genotypes (write the answer including two decimal figures) Absolute fitness (W) of AA= Absolute fitness (W) of Aa= Write the relative fitness for AA and Aa genotypes (write the answer in decimal numbers, include two decimal figures) Relative fitness (w) of AA= Relative fitness (w) of Aa= asap please.
- Explain why it does not make sense to try to separatethe effects of genes (“nature”) and the environment(“nurture”) in a single individual, while it does make senseto separate genetic and environmental effects on differencesamong individuals.Explain the trade-off between number of offspring and amount of parental investment per offspring. The trade-offs of parenting Parental investment expenditure of time and energy on one offspring Pros: parental investment may inorease the chances of an offspring to sunvive and reproduce w net l e Cons parental in vestmentreduces the parent's abilityb generate additional offspring Parental investmentis a limitedresource Why do males and females have different reproductive strategies? Why do males in many species employ a number-of-offspring strategy while females employ the parental investment strategy? Females are more likely to gain from parental investment: Evolution of sexual reproduction 1.

O Absolute Fitness O Mean Relative Fitness Selection Coefficient O Expected Genotype Frequency O Relative Fitness
- what are the key concepts of the fitness? proper explanation and diagramWhich of these individuals has the highest relative fitness? An individual that produces 999 offspring in a population where the average number of offspring is 1000 An individual that produces 5 offspring in a population where the average number of offspring is 1000 An individual that produces 5 offspring in a population where the average number of offspring is 4 An individual that produces no offspring, but has the highest muscle mass in populationWhich 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 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 progenyWhat is fitness? To what degree does fitness dependon the environment in which organisms live?Which of the following is a form of a heritable trait that enhances an individual’s fitness? Adaptation Lineage Fitness
