Q
The mechanism of evolution is the interaction between variation and…? (2)
A
Selection (Directional)
Drift (Random)
2
Q
What are the heritable cahnges in the genotype that give rise to the genetic variationneeded for evolution?
A
Indels/Substitutions (Both replication errors)
Transposition
Recombination
Gene duplication/loss
Gene flow between populations (Hybridisation)
3
Q
2 features of Microevolution
A
Small scale (few genes and small effects)
Changes allele frequencies (In population over generations)
4
Q
Whatare the 4 levels of informayion flow, in order?
A
Genome
Transcriptome
Proteome
Biochemistry of a cell
5
Q
What phenomenom defines the properties of DNA?
A
Base hydrogen bonding
(C:G 3)
(A:T 2)
6
Q
2 features of Macroevolution
A
Large changes in phenotype (Speciation)
Long timescales
