Evo Devo 2

Question 1

genetic toolkit

Answer 1

• hyper conserved, core set of genes that are shared over deep evolutionary time
• allows for the developmental modularity of organisms

Question 2

Gene Co- option

Answer 2

recycling of genes for new functions
the appearance of truly novel traits os almost always associated with co option of ancestral toolkit genes.
DII copies are homologs and peform similar but unique tasks

Question 3

Regulatory elements

Answer 3

parts of a gene that recieve inputs

Question 4

What is gene expression controlled by

Answer 4

• cis regulatory elements, the gene product doesn’t need to change- just when and where it is expressed
• Even skipped: codes for a protein
  cis regualtopry elements that tell the even skipped when to turn off

Question 5

cis regulatory elements

Answer 5

non coding regions of a gene that a transcription regulatory binds to.

Question 6

Recap

Answer 6

Evolutionary repurposing of old genes for new roles are co option or recruitment
Most conserved developmental toolkit genes play multiple roles during development
Trait evolution often occurs through changes in regulatory elements which leads to changes in gene expression,

Question 7

GWAS

Answer 7

genome wide association studies- technique that allows to identify genes that are responsible for phenotypic variation
