MECHANISMS OF EVOLUTION
Name 1 mechanism of evolution
Natural selection
Gene flow
genetic drift
mutation
non random mating
one of the type of evidence of evolution
FOSSIL EVIDENCE
COMPARATIVE ANATOMY
MOLECULAR BIOLOGY
EMBRYOLOGY
what does pre mean the word prezygotic
before fertilization
what is the relationship between allele frequency and genotype frequency
Hardy Weinberg equilibrium
what is natural selection
PROCESS WHERE TRAITS THAT HELP SURVIVAL BECOME MORE POPULAR OR COMMON IN A POPULATION
What is natural selection
When the individual with advantageous trait survives and reproduces
what is fossil evidence
snapshots of past life
Shows gradual changes over millions of years
Demonstrates extinction events and
biodiversity shifts
what does post mean in the word postzygotic
after fertilization
who is one guy that created this
G.H. hardy
W. Weinberg
what is the bell curve
a common type of disribution for a varible
What is an one example of one mechanisms of evolution
peppered moth natural selection
what is the difference between homologous and analogous structure
homologous structure Similar structures in different species.
ANALOGOUS STRUCTURES:SIMILAR FUNCTIONS, BUT DIFFERENT INTERNAL STRUCTURES
what is hybrid sterility
offspring is sterile
what does it help with
allow us to track a population genotypic and allelic frequency over time
what is directional selection
when the graph goes up left to right
whats the difference between genetic drift and gene flow
Gene flow is when the organism moves intentionally and Genetic drift when they are moved by a natural disasters.
wisdom tooth
appendix
what is hybrid inviability
offspring doesn't survive for long
Bonus: what is the equation for the Hardy weinberg
q2+2pq+p2=1
p=dominat allele frequency
q=recessive allele frequency
directional
stabilizing
disruptive
True or false: The bottle neck effect is apart of gene flow?
false
how many percent do we share our DNA with chimpanzees
98
what is sympatric
same location no physical barrier
what are the conditions of this
what is one example of natural selection
peppered moth
giraffes necks changing length
