Sexual and asexual reproduction

Cards (8)

  • Sexual reproduction involves the fusion of male and female gametes, a process known as fertilization, and results in offspring that are genetically different due to contributions from both parents.
  • Asexual reproduction, on the other hand, takes place with only one parent and doesn't involve any damage, meaning there's no mixing of genetic material and no genetic variation.
  • Eukaryotic organisms such as plants, fungi, and a few animals achieve asexual reproduction through mitosis.
  • Chaotic organisms such as bacteria asexually reproduce by binary fission.
  • Advantages of sexual reproduction include genetic variation, increased fitness due to recombination of genes from both parents, and ability to adapt to changing environments through natural selection.
  • Disadvantages of sexual reproduction include longer generation times compared to asexual reproduction, higher energy costs associated with producing sex cells (gametes), and potential loss of beneficial traits during meiosis.
  • Advantages of asexual reproduction include faster growth rates, shorter life cycles, and lower energy requirements compared to sexual reproduction.
  • Disadvantages of asexual reproduction include lack of genetic variation, reduced ability to adapt to environmental changes, and susceptibility to extinction if faced with sudden environmental change or disease outbreak.
