Selection & Mutation Notes
Describe selection against dominant alleles
Dominant traits are quickly selected against because the genotype will always display the
dominant allele. Thus it has no way of hiding or being silent.
Describe selection against rece
Life Span Notes
Selection's perfect organism would
1. be mature at birth
2. continuously produce lots of high-quality offspring
3. live forever
biology and physics impose limits on fitness
A constraint is something that plays the pa
Biogeography and Complex Characters
species-level & above; clade-level processes
-descendent species connected by populations through time
-evolution operates through extinction of species
-very long time-frames
Genome Evolution Notes
the various loci that make up a genome interact in interesting ways that deviate from the simple
model that we have been working with so far.
-this includes lateral transfer of genes across lineages and parasitic genes with
Origin of Life Notes
What is LUCA?
The Last Universal Common Ancestor.
-LUCA utilized DNA-Protein system with transcription, translation, etc.
-It is hypothesized that RNA may have been responsible for genetic replication before DNA
Cancer Study Guide
when proto-oncogenes mutate, they become cancer-causing genes
*called "gain of function mutations" because over expression is the result
Peyton Rous: Rous Sarcoma Virus
cancer can be transmitted by viruses: sarcomas removed fro
Sexual Selection Notes
fitness refers to both an organism's ability to survive and reproduce.
some traits may improve reproductive success while reducing survival.
Asymmetry keeps reproductive balance
-1 sex (often males
Quantitative Traits Part I Notes
H-W shows evolution leading to changes in genotype when.
1. we know the locus
2. when we know the number of alleles
3. we can recognize the genotypes
single loci of large effect
Patterns of Evolution Notes
looking at features across living taxa to infer history of change. this method does not need to rely
on fossils. Phylogenetic patterns can be used to test process hypothesis
