AS Biology - Types of variation: Discontinuous 0.0 / 5 ? BiologyDiscontinuous variationASAQA Created by: wahub aliCreated on: 31-01-17 15:39 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 6 of 6
