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.

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

|
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

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
