Explain how you would take a random sample
1) divide selected area into a numbered grid 2) use a random number table to select coordinates 3) place an appropirate sized quadrat at the coordinates selected
2 of 5
How will sample size affect the reliablity of your results?
the larger the sample size then the more reliable your results will be.
3 of 5
What will affect variation? what are the differences and influences?
Genetic differences: mutations, meiosis and fusion of gametes. Environmental influences: light, pH, food availabilty, soil conditions and climatic conditions

Describe mutuations, meiosis and fusion of gametes
mutations are the sudden changes to genes and chromosomes that may be passed onto the next generation, meiosis is a form of nuclear division that forms gametes, fusion of gametes will produce offspring with characteristics from each parent
