Explain why sexual selection results in sexual dimorphism, while natural selection does not.
(a) Sexual selection often leads to sexual dimorphism; this sometimes results in males being more colourful. Explain this under the good genes hypothesis (b) Focusing on males what is this type selection an example of (stabilising, directional or disruptive)? (c) Thinking about males and females what type of selection is this?
what force of evolution explains sexual dimorphism? why does this force of evolution sometimes result in traits that are counter intuitive from the point of view of natural selection?
Compare and contrast natural selection and sexual selection. What is the difference between intersexual and intrasexual selection? Give two examples of traits that are influenced by sexual selection and how they differ between males and females. How does the degree of sexual dimorphism in traits like these relate to the social organization of a particular species?
Why are sexual dimorphism and gregariousness often linked?
How is sexual selection different from natural selection, and why are the reproductive strategies of males and females different?

Why does the fitness of a phenotype depend on frequency-dependent selection? A. Because selection favors the least common phenotype. B. Because the least number of alleles are at that locus. C. Because sexual selection produces dimorphism. OD. Because frequency-dependent selection acts against extreme phenotypes.
Question 21 1 pts How does artificial selection differ from natural selection? the only real difference is that humans, and not the environment is doing the selecting artificial section does not result in the diversification of phenotypes natural selection is better for you because it is natural artincial selection takes longer Question 22 Which of the following breeding systems typically leads to sexual dimorphism, where the males are larger and/or more ornate than females? promisculty polysyny monogamy O polyandry A...
Briefly describe why natural selection results in bacteria that are resistant to antibiotics. How does this relate to the characteristics of life?
1. Describe how the process of natural selection works, and how it results in adaptations (Darwin's Observations and Conclusions) • How does unequal reproductive success lead to natural selection? What are adaptations? Explain Darwin’s observations and conclusions. • Describe evolution by natural selection? What are some important points about evolution? 2. Describe examples of and evidence for evolution by natural selection that can be seen in your daily life. 3. Discuss the different kinds of evidence that support the theory...
