neutral gene theory:
1-three classes?
---------
patterns expected?
---------
---------
When do we deviate from this model?
Give this one a try later!
mutations of genes have three classes
2-advantageous and very deletrious these don't contribute to
polymorphism
3-neutral which does (drift)
---------
1-high polymorphism; theta=4Neu (neutral) theta=polymorphism
2-polymoprhism increases with effective pop size
3-clock-like evolution
(freq of mutations= 1/2N; neutral=2Nu(netural); rate=u neutral *substitution
, rate= neutral mutation rate
--------
We deviate from the neutral when balancing or directional selection
occurs; when the population size changes
Broad Sense Heritability
vs
Narrow Sense
Give this one a try later!
Portion of phenotypic variance due to genotypic inheritance (vp/vg)
variance phen./ v genetypic
narrow sense: va/vp better way of predicting because this is more
predictable
1monogamy vs social monogamy
2polygamy vs polgyny
3forms of polygyny
4-which are rare out of polygamy, monogamy, polygyny, and polyandry
Give this one a try later!
1monogamy: true monogamy vs cheaters
2polygamy vs polygyny: multiple partners vs multiple ladies single male
3 scramble competition, female defense, resource defense, lek polygyny
(showboat area)
4- polygamy not rare, polyandry rare, monogamy-rare, polygyny- not rare
, selection differential
Response to selection
Give this one a try later!
t*= trait mean after selection
bar=mean before selection
the star made it through
R=response
S=selection differential
h2=narrow sense heritability
what is the ultimate source of variation?
what are the types of this source?
Give this one a try later!
mutation
point (silent vs replacement), insertion/deltion (frameshift if not three),
duplication, Chromosomal: insertion etc.; big deal
causes for altruistic behavior
Give this one a try later!
kin selection
recirpocation
manipulation
mutualism-not altruism
