clade
nodes and branches are called....

nada
MRCA & descendents
MCRA but not descendents
paraphyletic group
MRCA but not descendants
MRCA & descendents
does not include anything
polyphyletic group
does not include the MRCA of all members of the group
MRCA only
Descendents only
Parsimory
simple reason must be best reason
there is no reason
the most complicated reason is best reason
change in genetic makeup of a population overtime: descent with modification
evolution
natural selection
genotype
process in which individuals that have certain traits tend to survive and reproduce at higher rates than others
evolution
natural selection
Darwins Main points
Traits are heritable & more offspring are produced than can survive
Traits are not heritable & offspring are produced at equal rate
only offspring are produced than can survive
Population involve not individuals
False
True
Artificial Selection
Humans control over environment
Environment control
both human and natural selection control
Evolution is driven by ......
Mutations
Genetric Drift
Migration/ Gene Flow
all options
mutation results in ....
genetic variation
natural selection
gene flow
evolution
Bottleneck Effect
large population is drastically reduced by a non-selective disaster
small population is reduced by a non-selective disaster
population isolated from group
Founder Effect
few individuals become isolated from a large population and establish a new small population with a gene pool that differs from the large population
natural disaster
whole population becomes isolated and establishes new population elsewhere bc of natural disaster
Gene Flow
pollen transfer
flood
migration
