sexual and asexual reproduction 6.1.1

• sexual reproduction is reproduction involving the fusing of gametes (eg sperm and egg in animals or pollen and ovule (egg cell) in plants) there will be 2 parents
• asexual reproduction is reproduction that does not involve gametes and there is only one parent
• for sexual reproduction, the main type of cell division is meiosis
• for asexual reproduction the main type of cell division is mitosis
• in sexual reproduction the offspring show genetic variation
• in asexual reproduction the offspring do not show genetic variation
• in sexual reproduction, offspring inherit genetic information from both parents when the two gametes fuse
• gametes are produced by meiosis so all the gametes will be genetically different from each other
• the selection of which gametes fuse is random
• plants and microbes reproduce asexually through:

  • budding in yeast
  • binary fission in bacteria
• asexual reproduction does not involve sex between the parents
• sexual reproduction results in variation
• a clone is produced by asexual reproduction
• some plants can reproduce by both sexual and asexual reproduction
