Exp Design
A list of behaviors performed by the study species
that describes the functions and elements of each behavior.
What is an ethogram
______ is the nonrandom differential survival and reproduction of certain phenotypes based on selective pressures.
What is selection
The average reproduction output of all organisms bearing a given genotype
What is Fitness
_______ by natural selection can act ONLY on
heritable characteristics
What is Evolution
The two types of sampling
What is focal and scan sampling
Selection results in
What is adaptive evolution
The fittest group's relative fitness always equals ___
What is 1
Formula for heritability
What is h2 = Vg/Vp
or
h2 = Vg/(Vg + Ve)
This method of recording involves noting the frequency and/or duration of each behavior of interest.
What is continuous recording
One generation curve splits into two seperate curves for next generation.
What is disruptive selection
R(TT) = 20, R(Tt) = 35, R(tt) = 60. What is the relative fitness of TT.
What is 0.333
Highest possible value for h2
_______ behaviors are those that occur only briefly Prolonged behaviors can be categorized as a behavioral ______.
What is Event and State
An example of selective pressure
What is:
If R(TT) has a relative fitness of 0.8, how many alleles out of 10 do we expect to see in the next generation?
What is 8 alleles.
Heritability (h2): the proportion of
_________ variation in a population
attributable to ________ variation
What is: Heritability (h2): the proportion of
phenotypic variation in a population
attributable to genotypic variation
Example of an operational behavior definition.
What is:
How do you calculate selection differential
What is Population trait after event – population trait before event
If there are no differences in fitness, each genotype is ______ likeley to survive and reproduce.
All individuals in a population have the exact same allele that codes for a given phenotypic characteristic (aka that is the only allele present in the population). Ve = 0 for this trait in this population. The value of h2 is
What is 0
