Question
Chapter 23.2, Problem 3CC
Summary Introduction
To determine: The general effects of artificial selection in reference to figure 22.9, figure 22.10, and figure 22.11 given in the textbook.
Introduction: Evolution refers to the changes which can be transferred from the parents to the offsprings. Designing of procedures and programs in order to modify traits in domesticated species is known as artificial selection. In natural selection, parents able to survive and reproduce are selected naturally, whereas in artificial selection parents with desirable traits are selected by the breeder.

Using the concepts of variability, environmental pressure and natural selection how does the synthetic theory explain the darwinian natural selection?
VISUAL SKILLS Consider a population in which heterozygotes at a certain locus have an extreme phenotype(such as being larger than homozygotes) that confersa selective advantage. Compare this description to themodels of selection modes shown in Figure 23.13. Doesthis situation represent directional, disruptive, or stabilizing selection? Explain your answer.
Art Connections
Directions: With the knowledge you gained about the mechanism of evolution,
answer the following questions using illustrations/drawing. Write your
answers on a separate sheet of paper.
1. Give an example of natural selection that happens in your locality.
2. Where do you think genetic drift will likely happen more quickly on an
island or the mainland?
3. How do pollinators contribute to the gene flow?

- Why is mutation important to evolution if it is the microevolutionary force that generally has the smallest effect on allele frequencies?arrow_forwardQ1) We discussed the context in which evolution would likely favor the evolution of learning. Please describe how the predictability of cues (ie, the information value of cues) within ones own life (high or low) and the predictability of cues over many generations (high or low) would favor, or disfavor, the evolution of learning. You should briefly describe how the predictability of cues affects the evolution of learning, and, justify why they have the described effects on the evolution of learning. 2) Animals do not typically respond to the risks associated with foraging; they must obtain food regardless of risk. TRUE OR FALSE? 3) Many non-human animals, such as birds, exhibit a form of social learning called cultural transmission. TRUE OR FALSE?arrow_forwardWhat is the role of variation in evolution-if heterozygosity is reduced, what happens to the potential for evolution? The phenotype and genotype of a population is due to a mosaic of random and directed processe.some of these have to do with history; some are related to adaptation, etc. As completely as possibl, discuss the role of chance and direction in evolution and in determining the phenotype of a population.arrow_forward

Part A: Compare and contrast sexual selection, artificial selection, and natural selection.
