Cloning

• What should you know after studying this topic on cloning?

  You should know different ways of creating clones and why clones are useful.
• What is a clone?

  A clone is an individual that has been produced asexually and is genetically identical to the parent.
• Why are animals and plants chosen for cloning?

  They are usually chosen because of their high quality, such as disease resistance or high milk yield.
• What are the two main methods of cloning plants mentioned?

  • Taking cuttings
  • Tissue culture
• How do many plants reproduce naturally?

  Many plants reproduce naturally by cloning.
• What is tissue culture in plant cloning?

  Tissue culture is a modern way of cloning plants that allows the production of thousands of new plants from a small piece of plant tissue.
• What is the advantage of using tissue culture for cloning plants?

  It allows for the quick and easy production of thousands of identical plants from one small piece of tissue.
• What is the process of cloning animals described in the material?

  Cloning animals involves using embryo cloning to produce genetically identical offspring.
• How does embryo cloning work in cattle?

  Embryo cloning involves giving hormones to a cow to produce many eggs, fertilizing them, and then transplanting the embryos into host mothers.
• What is the significance of washing embryos out of the uterus during embryo cloning?

  It allows for the collection of embryos that can be transplanted into other cows.
• Why can every cell of an embryo form all the cells needed for a new cow?

  Because at this early stage of development, the cells have not yet become specialized.
• What is a benefit of cloning cattle embryos?


  It allows for the production of many top-quality calves each year.
• How can high-quality embryos be transported around the world?

  They can be carried to places where cattle are needed for breeding with local stock.
• What are the key points regarding cloning plants and animals?

  • Tissue culture is a modern technique for cloning plants.
  • Taking cuttings is an older method for producing identical plants.
  • Cloning cattle embryos involves splitting apart cells from a developing embryo.
  • Cloning is important for preserving rare plant species and for commercial use.
• What is the definition of asexual reproduction?

  Asexual reproduction is the process of producing offspring without the involvement of gametes.
• What is embryo cloning?

  Embryo cloning is the process of creating identical embryos from a single fertilized egg.
• What are some economic and ethical issues raised by embryo cloning in cattle?

  Economic issues include costs of procedures, while ethical issues involve animal welfare and genetic manipulation.
• What is the purpose of taking cuttings in plant cloning?

  Taking cuttings is used to produce many identical new plants from a parent plant.
• How does tissue culture help in preserving rare plant species?

  Tissue culture allows for the growth of identical plants, which can help maintain genetic diversity and preserve rare species.
• What is the flow of the embryo cloning process in cattle?

  The process involves hormone treatment, egg collection, fertilization, embryo washing, and transplantation into host mothers.
