      There is only one parent
    • What type of cell division is involved in asexual reproduction?
      Mitosis
    • How does the plant reproduce in the example given?
      By forming tiny buds
    • What is the genetic relationship between offspring plants and their parent in asexual reproduction?
      They are genetically identical
    • What are the main features of sexual reproduction?
      • Involves fusion of male and female gametes
      • Process called fertilization
      • Mixing of genetic information
      • Variation in offspring
    • What are the main features of asexual reproduction?
      • Involves only one parent
      • No gametes involved
      • Offspring are genetically identical (clones)
      • Only involves mitosis

    • What should you be able to describe by the end of the video?
      The structure of DNA and the genome
    • Why is it important to understand the human genome?
      It helps in searching for disease-linked genes
    • What will triple biology students study in more detail later?
      The structure of DNA
    • Where are chromosomes found in cells?
      In the nucleus of cells
    • What do chromosomes contain?
      The molecule DNA
    • Why is DNA referred to as genetic material?
      It determines our inherited features
    • What is the structure of DNA described as?
      A double helix
    • What forms the two strands of DNA?
      Polymers made of smaller molecules
    • What is a gene?
      A small section of DNA on a chromosome
    • What does the blood type gene determine?
      The protein that determines blood type

      Well over 700 different genes
    • What do both chromosomes in a pair have?
      The same genes
    • What is the genome?
      The entire genetic material of an organism
    • What is one benefit of studying the human genome?
      It helps search for disease-linked genes
    • How can understanding the human genome help with inherited disorders?
      It aids in understanding and treating them
    • What can the human genome be used to trace?
      Human migration patterns from the past
    • What can studying the human genome help people discover?
      Their ancestry
    • What are the key points about the structure of DNA?
      • DNA consists of two strands
      • Each strand is a polymer
      • Strands wrap around to form a double helix
