AQA Biology-Genetic Diversity and Adaptation: Types of variation

HideShow resource information
Continuous variation - How do they appear/exist?
They exist in a smooth series of many phenotypic intermediates
1 of 6
Continuous variation - How are they measured?
They're measured quantitatively. (ie numbers)
2 of 6
Continuous variation - What is the genetic behind Continuous variation?
They're Polygenic
3 of 6
Continuous variation - What does the term polygenic mean?
Means more than one gene usually contributes to that one phenotype
4 of 6
Continuous variation - what does it mean when alleles of these polygenic genes might have an additive?
Means that each gene contributes by a little amount of the phenotype
5 of 6
Continuous variation - What happens if there's a greater number of gene loci?
There's a greater range of character of characteristics
