- 6. Read the following sentence: “Even though people selectively breed to yield animals with desired traits, there are dangers to selective breeding.” What does yield mean as used in the text? a) To produce b) To surrender c) To endanger d) Not worth much money to remove20. A large population of laboratory animals has been allowed to breed randomly for a number of generations. After several generations, 25% of the animals display a recessive trait (aa), the same percentage as at the beginning of the breeding program. The rest of the animals show the dominant phenotype, with heterozygotes indistinguishable from the homozygous dominants. What proportion of the population is probably heterozygous (Aa) for this trait? (LS3-3) * 0.05 0.25 0.50 O 0.753. Can the populations make hybrid offspring? Is there evidence that individuals from the popula- tions interbreed to make hybrid offspring? If so, are the offspring plentiful, healthy, and able to reproduce? Example: Lions and tigers don't normally mate in nature, but in captivity they sometimes produce hybrid offspring. These offspring are rare, short-lived, and unable to reproduce. Evidence: Healthy offspring Offspring are rare or less likely to reproduce No Consider the evidence together. Do you think the populations make healthy hybrid offspring? offspring N/A 1 2 3 4 5
- 1. Early hunter-gatherers were interbreeding with colonists who brought agriculture from the Middle East. Did genetic adaptations of agriculturalists, such as the ability to digest milk as an adult, might have undergone genetic recombination with genetic adaptations of hunter-gatherers to potentially create a better adapted population in terms of survival and reproductive success? Why or why not?2. What does NOT happen to the hybrid zone when gene flow is established? O Hybrids cease to form. Reproductive barriers become weak. O Hybrid production continues. A population merges with another population.4. The roof rat (Rattus rattus) and the Norway rat (Rattus norvegicus) are unable to interbreed because their F1 progeny die during embryogenesis. This type of reproductive isolation is best described as: A. a post-zygotic barrier known as behavioral F, inferiority B. a post-zygotic barrier known as F, hybrid breakdown C. a post-zygotic barrier known as ecological F, inferiority D. a post-zygotic barrier known as F, hybrid sterility E. a post-zygotic barrier known as F, hybrid inviability
- 1. What is the expected time to fixation in generations for a new mutation in a diploid population (like humans) with an effective population size of 50? This new mutation is neutral and has no impact on fitness (e.g. synonymous polymorphism). Assuming the mutation isn’t lost immediately, will it reach fixation faster in a population of Ne=500 or Ne=5,000 and why?8. Imagine that you collected individuals of a species of hydra and established six replicate populations in your lab at home. In the wild, this species carries a few bacterial parasites, but after creating your six populations, you treat each with antibiotics, and eliminate all bacterial parasites. At every fifth generation, you record rates of outcrossing in each population, and plot your data below: (7) 10 15 30 Generation a. Describe what happened to the rate of outcrossing over time. b. Explain two advantages to changing rates of sexual reproduction in this direction. c. Imagine that you reintroduce bacterial parasites to each population in generation 30. Predict how outcrossing rates will change by extending the x-axis, above, and plotting outcrossing rates for generations 35 – 45. Outcrossing Rate 0.2 0.4 0.6 0.8 20 251. Explain in 200 words how the Darwinian evolution can decrease or increase the frequency of an allele( or a more complex heritable trait, for that matter).
- 1. What is the percentage heterozygosity remaining in a bottlenecked population of 25 individuals after one, five and ten generations?28. How is Darwinian “fitness” different than the typical definition used in common speech?1. Why would a population with no genetic variation and unlimited resources never be expected to evolve?
