1 of 14
What is the acronym for the 6 types of Variation?
CEDGII
2 of 14
What does CEDGII stand for?
Continuous, Environmental, Discontinuous, Genetic, Interspecific and Intraspecific
3 of 14
What is Continuous variation?
Variation where there are 2 extremes and a full range of values in between
4 of 14
What is Discontinuous Variation?
Where there are distinct categories and nothing in between
5 of 14
What is Environmental Variation?
Variation caused by response to environmental factors such as light intensity
6 of 14
What is Genetic Variation?
Variation caused by possessing a different combination of alleles
7 of 14
What is Interspecific variation?
The differences between species
8 of 14
What is Intraspecific Variation?
The variation between members of the same species
9 of 14
What is Continuous variation often regulated by and what can influence it?
Often regulated by more than one gene and can be influenced by the environment in which the organism lives
10 of 14
What is Discontinuous variation usually regulated by and what doesn't influence it?
Often regulated by a single gene and the environment in which the organism lives doesn't influence it
11 of 14
What are the 2 general causes of variation?
Genetic and Envrionmental
12 of 14
What is genetic variation?
The combination of alleles that we inherit is not the same as that in any other living thing
13 of 14
What is Environmental variation?
Characteristics that are affected by the environment. E.g. exposure to sun causes skin to tan
