Evo Devo Flashcards
What mechanisms might generate complex characteristics?
Evolutionary Developmental Biology (Evo Devo)
Has there been a documented similarity between various animal embryos?
Yes
In order to establish an homology, what must be critically present?
Similarity in animal embryos
Complete this analogy: Animal Embryo: _____
Evolutionary change
Explain the phrase “Ontogeny Recapitulates Phylogeny.”
The development of an organism (ontogeny) expresses all intermediate forms of its ancestors through evolution (phylogeny)
What do master genes control?
Where, when and how other genes are expressed
Explain a function of a master gene.
A master gene makes proteins that communicate with other genes and their products
What type of pattern are master genes expressed in?
A sequentially set pattern
Name two other names for master genes.
- Homeotic (HOX) Gene
2. Developmental Regulatory Genes
What do homeotic genes regulate?
The development of anatomical structures in various organisms via the programming of varies transcription factors by the homeotic genes.
Where do transcription factors by the homeotic genes affect genes?
Affect genes through regulatory genetic pathways
