BIOL 320 COMPREHENSIVE EXAM 2026 UPDATED
QUESTIONS AND ANSWERS GRADED A+
✔✔Rough skin newt example:
Reproductive success in female newts is not limited by the number of males that they
can mate with but rather ? - ✔✔How many eggs an individual female can produce
✔✔What is the previous situation called? - ✔✔physiological constraint
✔✔Rough skin Newt Example:
Males on the other hand, are limited to their reproductive success by the number of
females they can mate with, this results in what - ✔✔competition among males for
access to the females
✔✔what is this an example of? - ✔✔intrasexual selection or competiton
✔✔the nearly neutral model of evolution attempts to explain the observation that many
genes appear to be evolving at similiar rates in different organisms. Part of the basis for
this model is the lower subceptibility of large populations to genetic drift is balanced or
offset by: - ✔✔The higher susceptibility of small populations to genetic drift
✔✔Direct fitness - ✔✔Fitness that results from your own reproductive success
✔✔indirect fitness - ✔✔fitness that results from the reproductive success of your
siblings and cousins
✔✔inclusive fitness - ✔✔overall fitness combo of both
✔✔Inbreeding increases the frequency of - ✔✔homozygous genotypes in a population
✔✔Inbreeding reduces the frequency of - ✔✔heterozygous genotypes
✔✔What does not have the potential to change allele frequencies within a population
from one generation to the next - ✔✔inbreeding
✔✔which of mechanisms of evolution is adadptive - ✔✔natural selection
✔✔pahoa kipuka chicken, - ✔✔
✔✔ positive selection - ✔✔greater than 1 non-syn/syn
✔✔negative selection - ✔✔less than 1 non-syn/syn
