Step by step
Solved in 3 steps
- Which of the following contribute to keeping low-fitness alleles in our gene pool? Choose all that are correct Random mating Efficient selection against rare recessive disease-causing alleles New mutations Late age of onset of some diseases Inefficient selection against rare recessive disease-causing allelesWhy is negative selection important?This type of selection favors individuals with alleles at both end of the spectrum of Traits
- What would happen if a mutation created a new allele that decreased fitness? * The new allele would have to change back to an allele of higher fitness so the possessor of that allele could maintain its fitness. The individual with the new allele would wait for an environmental change so that its fitness would increase again No answer The new allele would decrease the fitness of the individual that possessed it, and that individual would have few or no offspring The new allele would spread through the population and decrease the fitness of that populationWhich of the following statements about genetic fitness and/or selection is false? Group of answer choices Individuals with low fitness have greater selection coefficients Fitness involves both relative viability and reproductive success Individuals with high fitness have greater selection coefficients Selection against recessive alleles tends to be slower overall than dominant alleles because of the survival in heterozygotesWhat type of selection reduces genetic variation in a trait? disruptive? balancing? directional? stabilizing? Explain why
- A freshwater fish called the blue danio (Danio kerri) has pink stripes down its sides. What has to be true about color pattern in these fish for it to be subject to natural selection? Group of answer choices It can only be a trait that is due to one gene that only has 2 alleles. It must be identical in all individuals in the population. It must be derived from their diet – it can’t be a genetically-based trait. It must be a genetically-based trait. It must be present in males but not in females.Which of the following is a reason we see continuous, quantitative traits like weight? - Environment doesn't play a role in quantitative traits - Multiple genes can play a role in determining the traits - Only one allele on one gene is responsible for a given quantitative trait - Natural selection doesn't act on quantitative traitsHow can natural selection maintain harmful alleles in a population?
- A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? O increased variation in the shades of red because there is no advantage in one specific color increased variation in the shades of red because the cardinals try different ways to impress the females decreased variation in the shades of red over time because no form of the trait is advantageous decreased variation in the shades of red after a single generationUnder which of the following scenarios would variation be maintained? Selection acting on a dominant high fitness allele Selection acting on a recessive high fitness allele Selection favoring heterozygotes Selection acting against heterozygotes None of the aboveIn the following form of selection, one extreme of a variable character is selected for: Directional Selection Stabilizing Selection Disruptive Selection
