LS 15 FINAL STUDYGUIDE EXAM WITH
CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+ 2025 – 2026
What is revealed preference and why is it important? - ANSWERS-
Looking at people's actual behavior rather than asking them what
they prefer (they could contradict each other)
What are STR loci and how do they differ? Use this in a description
of how DNA fingerprinting works. - ANSWERS-STR are short random
repeats (ex. CCG, ATG) usually 4-5 nucleotides long, many alleles
exist in the population but an individual can only have two of them
How DNA fingerprinting works:
-The DNA fragment containing each STR region is amplified using
PCR. this results in huge numbers of those fragments
-The fragments are separated by size using electrophoresis
, - Run gel (put DNA duplicated samples in the gel, then have electric
charge that passes current through, neg DNA flows through
How is the culture/biology interplay illustrated by constrained
learning? - ANSWERS-we cannot learn everything some things are
limited by biology due to constrained learning. better at learning
things that have evolutionary significance. Sauce Bearnaise
Phenomenon
Ex: Mice have "genetically coded hypothesis" that automatically
says "if I feel sick it must be something I ate".
Gave two experiments: Mice were able to learn not to drink water
b/c of possible correlation
1. Mice drank water--> noise & lights--> electric shock
2. Mice drank water--> weird taste--> nausea induced by x-rays
Changed experiments: Mice were unable to learn not to drink water
b/c no biological relationship between them
What is the EEA? And why is it important for us to be aware of it? -
ANSWERS-Environment of Evolutionary Adaptiveness
The world we are adapted to through natural selection where
instinct will lead you to the right outcome, once you are put in a
different environment instinct are not as efficient
Why is EEA sometimes different from our current environment? -
ANSWERS-Evolution is slow & culture and technology can cause the
environment to change quickly
