Evolutionary Biology 12: Evo Devo Flashcards
1
Q
Models of functional outcomes of duplicate genes
A
Pseudoginization
Redundancy
Subfunctionalisation
Neofunctionalisation
2
Q
What does carroll believe is the main driving factor for genetic evolution?
A
Changes in the regulatory regions in genes (non-coding regions) that effect expression at different times, areas etc.
e.g. Pax-6 gene, only tiny amount of gene is actually exon
3
Q
Famous example of homologous gene across species and difference in function?
A
OPTIX - master regulator of eye development in Drosophila
Ectopic expression of OPTIX can induce eye formation
OPTIX also identified as red colouring regulator in butterfy wing pattern
