2) Heritability
3) Fitness
___________ exists among individuals in a population in the traits they possess.
a) Variation
b) Heritability
c) Evolution
d) Fitness
Variation
Individuals different traits are at least in part, _________
a) Variation

c) Evolution
d) Fitness
Heritable
Traits confer differences in SURVIVORSHIP a measure we call?
a) Variation
b) Heritability
c) Evolution
d) Fitness
Fitness
What are the measures of heritability?
a) Selection of method
b) Genetic composition
c) Parent-offspring regression analysis
d) A and C
A and C
What is the statistical technique that assesses SIMILARITY OF TRAITS between parent and offspring? If the trait is heritable, the of values of offspring is __________ to value of patents. This is called?
1) Parent offspring recession analysis
2) Similar
3) Positive correlation
What is it called when different groups subjected to DIFFERENTIAL SELECTION? If selection changes trait value, then traits has __________ __________
1) Flection experiment method
2) Genetic basis
Maternal defense in mice (make sure to go back to page 17 to see graphs)
1) Half randomly chosen as control line/half selection line
2)Tested real defense behavior 4-6 days post partum:
-Placed unfamiliar male in female cage
-Recorded duration of her attacks on male
3) Only females with longest attack duration mated; for control line, random mating
4) Continued for 8 generations
What experiment was tested?
a) Parent-offspring recession
b) Selection experiment
c) Genetic composition
d) Environmental conditions
b) Selection experiment
Maternal defense in mice (make sure to go back to page 17 to see graphs)
-Analyzed female attack behavior of initial parental generation and their offspring.
What experiment was tested?
a) Parent-offspring recession
b) Selection experiment
c) Genetic composition
d) Environmental conditions
a) Parent-offspring recession
What is it called when there is a difference in a feature due to genetics?
Ex) Eye color
a) Heritability
b) stabilizing selection
c) polymorphism
d) polypheniesm
Polymorphism
What is it called when a morph is triggered by the ENVIRONMENT? It is when a single genotype codes for different phenotypes caused by environmental variables. Switch gene turn on or off?
Trigger for this:
1) Amount of food
2) Type of food
3) Social interaction (fish gender, territoriality)
4) Presence of Predator
a) Heritability
b) stabilizing selection
c) polymorphism
d) polypheniesm
Polyphenisms
Male cichlids can be colorful or drab. Colorful defend territories and drab are submissive. When separated, drab male becomes colorful and reproductive.
What is this called?
a) Socially induced polypheniesm
b) Food induced polypheniesm
c) predator induced polypheniesm
d) frequency dependent selection
Socially- induced polypheniesm
What is it called when the fitness of a trait is linked to the frequency in a population?
a) Socially induced polypheniesm
b) Food induced polypheniesm
c) predator induced polypheniesm
d) frequency dependent selection
Frequency dependent selection
A salamander species have stripes and some don’t have stripes. This is an example of what?
a) Stabilizing selection
b) Directional selection
c) Polymorphism
d) Polypheniesm
Polymorphism
