what kis ka kspecies?
A kbiological kspecies kis ka kgroup kof korganisms kthat kcan kreproduce kwith kone kanother
kin knature kand kproduce kfertile koffspring.
What kis kevolution? kDefine kit kbroadly kand kspecifically. kThe kspecific kdefinition kshould
khelp
someone kmeasure kif kevolution kis khappening kor knot.
The kprocess kby kwhich kliving korganisms kchange kand kdevelop kover ktime.
How kare kecology k(the kstudy kof khow korganisms kinteract kwith keach kother kand ktheir
kenvironment) kand kevolution kconnected
The kdevelopment kof ka kspecies koccurs kdue kto kthe kecological krelationship kof
ka kspecies
with kanother kspecies kin ktheir khabitat kand kthe kenvironment kplays ka kcrucial
krole kin
affecting kthe kevolution kthrough knatural kselection.
What kare kthe kfour kmechanisms kof kevolution?
Natural kselection
Migration
Mutation
Genetic kDrift
What kare kthe krequirements kfor kevolution kby knatural kselection kto koccur?
Natural kselection
Migration
Mutation
Genetic kDrift
What kis kthe k"modern ksynthesis"?
The kintegration kof kgenetics kand kevolution---the kcoherent kunderstanding kof kthe
krelationship
between knatural kselection kand kgenetics.
Mendelian kgenetics kdescribes kthe ktransmission kof k_____________ kfrom kindividual
kparents kto kindividual koffspring
Is kit kan kevolutionary kforce?
, Mendelian kgenetics kdescribes kthe ktransmission kof kalleles kfrom kindividual kparents
kto kindividual koffspring
NOT kand kevolutionary kforce....
Population kgenetics kdescribes kthe ktransmission kof kalleles kin ka kpopulation kfrom kone
k______________ kto kthe knext.
Population kgenetics kdescribes kthe ktransmission kofalleles kin ka kpopulation kfrom kone
kgeneration kto kthe knext.
REVIEW: kCalculating kprobabilities:the kAND krule k& kthe kOR krule------
If kyou kflip ka k(fair) kcoin ktwice:
1. kWhat kis kthe kprobability kthat kyou kobtain k2 kheads?
2. kWhat kis kthe kprobability kthat kyou kobtain k1 kheads kand k1 ktails?
1. kOn kthe kfirst kflip kthere kis ka k50% kchance kwe kwill kget kheads k(we kcan kwrite kthat
kas ka kfraction k1/2) kon kthe ksecond kflip kthere kis kalso ka k50% kchance k(written kas k1/2)
The kAND krule ktells kus kto kmultiply kthese kvalues
1/2 kx k1/2= k1/4
2. kthere kis kno kspecified korder kin kwhich kwe kneed kto kget keither kof kthem kfirst----------
kOR ktells kus kto kadd kthem.
So kprobability kof kgetting kheads kthen ktails k= k1/2 k+ k1/2 k= k1/4 k= k1/2
Proability kof kgetting ktails k= k1/2 kthen kheads k= k1/2
So k1/2 k+ k1/2 k= k1/4 k=1/2
What kis kallele kfrequency? kGive kan kexample.
Allele kfrequency kis ka kterm kused kin kgenetics kto kdescribe kthe krelative kabundance kor
kprevalence kof ka kspecific kallele k(a kvariant kof ka kgene) kin ka kpopulation. kAlleles kare
kdifferent kforms kof ka kgene k(EX kAA, kAa, kaa) kthat kcan klead kto kvariations kin ka
kparticular ktrait kor kcharacteristic.
