Q

Sexual Selection: Direct Benefit Theory (5)

A
  • Females are choosy because they have more to lose
  • Females want best genes to best have chance of having more success
  • Males must sell self using best phenotypes
  • Males are mostly average but it is a standard distribution (some better, some worse)
  • Males must bring direct benefits ( presents, etc…)

Q

Good Gene Theory: Assumptions (2)

A
  • Females must be able to ID the best genes based on phenotypes
  • Females must ID cheaters
84
Q

Good Gene Theory: Cheating to get mates (2)

A

-honest signals of healthy/ fit males is extremely costly
-Therefore honest phenotypes are a handicap
Handicap Hypothesis

85
Q

Handicap Principle/ hypothesis (1 + example)

A

An honest phenotype would hinder survival to get a mate

Ex. Peacocks tail
-paradoxical (shouldnt be alive with the bulky tail but I am so I should be fit)

86
Q

Good Gene Theory: How females detect good genes? (2 ways)

A

-better phenotypes = less parasites = better immune system
-high parasite load makes them look less fit
Hamilton-Zuk Hypothesis

MHC pheromones: genetically determined smell (fingerprint smell)
-Females likely pick up on the smell, may discriminate the males immune system

87
Q

Good Gene Theory: Hamilton-Zuk hypothesis (2)

A
  • Females choose the least parasitized males

- Means they have better immune system

88
Q

Good Gene Theory: MHC Pheromones (2)

A
  • genetic signature, therefore can smell how closely related organisms are
  • this helps dodge inbreeding
  • look for a mismatch
89
Q

Good Gene Theory: Fluctuating asymmetry hypothesis (3)

A
  • more symmetrical = more fit
  • humans find symmetrical faces most attractive
  • symmetry and odour may be correlated
90
Q

Good Gene Theory: Fluctuating asymmetry hypothesis - Example (2)

A

-Birds may have excellent olfactory to judge mates, young in eggs, etc..

91
Q

Runaway Selection Theory (5)

A
  • two genes are involved (one expressed on each sexes side)
  • both genes in each sex but only one expressed based on their sex
  • The gene in females sets a preference to something
  • The gene in males has a gene that inherits the female preference
  • Better inheritance of the preferred gene and this causes a runaway to exaggerated this preferred trait
92
Q

Runaway Selection Theory: genes used in this theory

A

Likely genes that express ornaments

93
Q

Other factors in mate choice (3)

A

Learning
Sexual Imprinting
Cultural transmission

94
Q

Other factors in mate choice: Learning (3 + example)

A
  • Classical or instrumental conditioning
  • Young females choose mates based on how experienced females do
  • Could influence choice (not just innate)

Harlow experiemnts: isolated baby monkey (they didnt learn about sex, etc..)

95
Q

Other factors in mate choice: Sexual imprinting (4)

A
  • chics imprint when born (follow that)
    -Mammals have something similar too
    (Filial imprinting)
    -closer to puberty sexual imprinting occurs (see what to ‘like’)
96
Q

Other factors in mate choice: Cultural Transmission (5)

A
  • Females may show to other females on what to pick
  • Genetic transmission of this knowledge is possible too
  • If this is true: many females will copy the matriarch
  • Then the males that mate will be fewer and some males will have even more success
  • Leads to more reproductive success variance
97
Q

Other factors in mate choice: Cultural Transmission issues (2)

A

Copiers copying copiers is not helpful

Can be maladaptive

98
Q

Sexual Selection: Good Gene Theory Example: Barn Sawllows

A
  • Long tails handicap the birds survival
  • Long tails indicate parasitic resistance
  • But tail could even be advantageous (seen in wind tunnel)
99
Q

Sensory Bias Theory: What kind of approach?

A

Proximate approach

100
Q

Sensory Bias Theory (2)

A
  • Choice in female driven by the intensity of the sensory simulation
  • respond to specific, predisposed sensory stimuli
101
Q

Sensory Bias Theory: Swordtails (3)

A
  • Xiphophorus genus: No all species have these swords
  • However, female in species without a sword are more interested in the opposite species with swords
  • These females responding to an ancestral gene for that preference
102
Q

Sensory Bias Theory: Mallard Ducks + Others in NS (3)

A
  • Mallard ducks are not from Canada (the males are very bright colours)
  • Female Black Ducks in NS are attracted to Mallards more than their own species
  • Male Black Ducks are not colourful
103
Q

Hybridizing: Climate Change (2)

A
  • Due to climate changes, species are beginning to overlap and hybridizing
  • Ex. Grizzly + Polar

-Sensory Bias Theory may play a role in this in the future

104
Q

Pinniped Sexual Dimorphism (2)

A
  • Males much, much bigger than females

- Males can have ornaments too often

105
Q

Ornaments: uses (3)

A
  • Impress females
  • Assessment of other males
  • Intimidation of other males
106
Q

Ornaments and Androgens: Connection (3)

A
  • Ornaments could be linked to androgens
  • Ie. Bigger/better ornament = more androgens
  • Moose horns are linked to androgens 100%
107
Q

When does testosterone / Androgens peak? (2)

A
  • Right before mating season

- To deal with competition

108
Q

Forced Mating (4)

A
  • Happens in Elephant Seals, often
