Discontinuous variation - How do they appear/exist?
The phenotypes fall into discrete (easy to separate) fall into classes/categories
1 of 6
Discontinuous variation - How are they measured?
Qualitative measures are utilised to measure these types of characteristics
2 of 6
Discontinuous variation - What is the genetic behind Continuous variation?
They're Monogenic
3 of 6
Discontinuous variation -What does the term monogenic mean?
Only one gene contributes to each of the phenotypes
4 of 6
Discontinuous variation -What happens if it's not a monogenic gene and so what will this then not have as a result?
Different loci have large and differing effects on phenotype, thus it will not have an additive effect
5 of 6
Discontinuous variation - what can this type of variation cause as a result and what does this cause mean?
This type of variation causes Epistasis which is where a few genes interact together to form a phenotype in order to influence only ONE characteristic
