meiosis

• +

  • Meiosis allows for the formation of genetically varied gametes, made up of differing combinations of alleles, which fertilise to eventually develop genetically varied offspring.
• +

  • This is advantageous because it increases genetic diversity and decreases the homogeneity of a population, which increases the likelihood of the population adapting to a potential selective pressure.
• +

  • As a result, this enables the population to thrive in its environment and continue to reproduce, ultimately contributing to the continuity of the species.
• -

  • Favourable traits in the species are not guaranteed to be passed on to offspring due to variation in gametes.
