- heritability
- traits passed on from one generation to the next based on success of that trait within a indvivdual
- delta 32
- ccr5 protein that is resistant to hiv. named 32 because of its 32 bases
- coelacanth
- sarcopterygian , first discoverd by marjorie latimer and sent to jp smith where it was studied dr. mark erdman would later find it in the indonesian fish market on his honeymoon.
- psudeogenes
- homologous to functioning genes. used in molecular homoology study
- theory of special creation
-
creationist biblical view.
1-animals non mutable
2-animals distinct from one another
3-god created earth recently - second law of thermodynamics
- in every physical or chemical change, universe always tends towards greater randomness or disorder
- polyploidy
- being able to have multiple chromosomes. like a tetraploid who can reproduce by its self. often lead to new plant species. prevelant in plants
- vestigal structure
- rudimentary traits that are homologous to to fully functional traits in a closely related species.
- gel electrophoresis
- dna fingerprinting. use electric charges to determine different proteins or spots on the gel. the smaller and lighter elements move faster than the heavier and big ones.
- virion
- hiv. an infectous extracellular virus
- relative dating
- for age of fossils., using rock strata. like superposistion, horizontal lines, faunal succesion, and cross shifting
- frameshift mutation
- insertion or deletion of a base in a sequence of dna. can mess up remaining of dna sequence.
- darwins four postulates
-
variation within indviduals
variation is heritable
variation can lead to reproductive success in indvieduals and better traits for survival
survival is not random - hw assumptions
-
no migration
no mutation
no selection
infinite pop size
random mating - frequency dependent selection
- level of selection aganist a phenotype depends on the prevleance of the phenotype in the population
