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.

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?
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.

Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificialselection? How is it different?3.

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
- When discussing natural selection and behaviour, we often say that members of a species have certain behavioural traits because those traits are adaptive, in the sense that they increase inclusive fitness relative to alternative forms of those traits that have existed in the past. Instead of emphasizing the adaptiveness of behavioural traits, some biologists describe natural selection as a process that operates on nervous system traits, increasing the prevalence within a population of particular patterns of neural circuitry and neurobiological mechanisms. As an alternative to emphasizing either the behaviour or the nervous system, some biologists describe natural selection as a process that operates on genes; according to this perspective, certain forms of certain genes (ie., particular alleles) increase in prevalence within a population relative to alternative forms of those genes. Which, if any, of these three perspectives on natural selection and behaviour do you think is the most…arrow_forwardDirections: Perform the task below based on your understanding on the topic " Mechanisms 'of Evolutionary Change" .
