Some advantages of asexual reproduction are
– Large numbers of offspring are reproduced very quickly from only one
parent when conditions are favourable.
– Large colonies can form that can out – complete other organisms for nutrients and water.
– Large numbers of organisms mean that species may survive when conditions or the number of predators change.
– Energy is not required to find a mate.

Some disadvantages of asexual reproduction are
– Offspring are genetic clones. A negative mutation can make a sexually produced organisms susceptible to disease and can destroy large numbers of offspring.
– Some methods of asexual reproduction produce offspring that are close together and compete for food and space.
– Unfavourable conditions such as extreme temperatures can wipe out entire colonies.


 Sexual Reproduction

Define sexual reproduction as the process involving the fusion of haploid nuclei to form a diploid zygote and the production of genetically dissimilar offspring

Life cycle- mitosis and meiosis

Sexual reproduction can take many forms like this!





Some Advantages of sexual reproduction are:

  • Genetic variation (the ability of organisms to adapt over time). Due to the fusing of gametes (one from each parent), the offspring displays a mixture of traits.
  • Two parents are required

Some Disadvantages of sexual reproduction are:

  • Energy must be consumed to find a suitable mate.
  • Mutations may occur
  • Not as rapid and efficient as other forms of reproduction (eg binary fission)
  • Very few offspring produced at a time
