In this activity, students carry out a genetics webquest using resources from the Science Learning Hub or a genetics animation from the Learn Genetics website.

By the end of this activity, students should be able to:

  • explain the key terms chromosome, DNA, gene, trait, genotype and phenotype
  • describe where DNA is found in the body
  • explain that genes code for specific proteins
  • explain the basic concept of inheritance – that parents pass chromosomes on to their children
  • explain how our phenotypes are a result of an interaction between genetic make-up and environmental factors
  • give some examples of environmental factors that affect our phenotypes.
