Watch BBC video clip about chemical analysis and its use in classifying organisms (see resources). WS 1.1 Show how new methods of investigation and new discoveries led to new scientific ideas How are species and biodiversity connected? Students show similarities and differences between whales and sharks, snakes and in diagrammatic form. 4.4.4.5 Selective breeding (artificial selection) is the process by which humans breed plants and animals for particular genetic traits. Selective breeding involves choosing parents from a mixed population with the desired characteristic. They are bred together. From the offspring those with the desired characteristic are bred together. This continues over many generations until all the offspring show the desired characteristic. Explain why humans selectively breed plants and animals. Describe selective breeding as a type of sexual reproduction. Describe the process of selective breeding and give examples. Explain the benefits and risks of selective breeding in plants and animals. 1 Images of different dogs. Students ‘breed’ and name a new dog from selecting any two – draw a picture of their new breed. Draw a flow diagram to explain the involved in selective breeding. Give examples of characteristics that are selectively bred in plants and animals. Discuss the advantages and risks of selective breeding in plants and animals. Produce a model to describe selective breeding. What was special about the race horse Frankel? Why is artificial insemination not used in the horse racing industry? Consider the social, economic and ethical implications of selective breeding. clips:
