What are indirect fitness benefits of siblicide? When would an individual gain more from siblicide than from inclusive fitness benefits? When might it be worth it for a subordinate to fight to the death with its dominant sibling?

What is the frequency of winged dragons? (take # winged / total dragons)

Prairie dogs exhibit a behavior that appears to be contrary to that of natural selection. One will act as a lookout for the others of the community, demonstrating a warning call when observing an eagle flying overhead. This loud noise calls attention to himself which puts him more in harms way than if he ran to hide discretely. However, the warning call allows the others of his community to react and protect themselves. This selfless act is an example of imprinting innate behavior altruistic behavior classical conditioning 500

Which of the following are equivalent ways to talk about an allele or genotype of individuals who are able to leave MORE offspring than others in a certain environment? Check all that apply. Group of answer choices A-"has a benefit"   B-"has a higher fitness"   C-"confers a selective disadvantage"   D-"confers a selective advantage"   E-"has a cost"

You do not need the text from the image so font size does not matter. Please consider the figure, which contains data that were collected by Rice In the experiments that were performed by Ricei. males competed intensely for females, which resulted in selection for traits like 'high likelihood to remate with the same female' and 'high proportion among fertilised eggs fathered.'ii. only males experienced intense competition; females were obtained from a control population, in which no competition for mates was occurring, effectively fixing female responses.iii. males that were selected for success in mating competition were characterised by greater fitness.iv. when females were prevented from evolving compensatory life history traits, they incurred at least one cost for the benefits gained by males in increased reproductive success:  greater female mortality (attributed to toxicity in male seminal fluid).v. once established, enhanced male traits were irreversible.   Question 4…

Based on coefficients of relatedness, would a person be more likely to behave altruistically towards a cousin or a niece?

The coefficient of relatedness between you and your uncle on your dad's side is O 0.25 O 0.5 0.125 O 0.75

Use examples to explain sexual selection and its outcomes.

Among the Great Apes, yet unlike our chimpanzee and bonobo 'cousins', as humans we combine a unique evolutionary blend of different physical and behavioral traits commonly identified with either 'pair-bonding' or 'tournament' species. Which of the following options below inaccurately matches our shared characteristics with each type? Select one: a. moderate to high degree of sexual dimorphisms - tournament b. moderate to highly monogamy in coupled relationships - tournament c. male mate pickiness - pair bonding d. high parental investment - pair bonding e. females selecting mates for parenting skill - pair bonding f. moderate to high variability in male reproductive success & aggression - tournament
