AQA Biology A Level Student Book notes

Define variation - correct answer. Differences that exist between individuals In what ways can variation be caused? - correct answer. It can be caused by genetic factors, such as alleles from mutations. It can also be caused by the environment, such as climate. Most variation is caused by a combination of genetic factors and environmental factors Why is it impossible to study a whole population? - correct answer. Because it is too large and would take too long. Instead, scientists use a ...
