Exam- Biology 1108- Exam 1(Chapters: 21-24, 27-28)
Questions and Answers
A population with a novel adaptation has evolved that adaptation T or F CORRECT ANS-
True
polytomy CORRECT ANS-a graphical depiction of what type of relationship there is
between groups
Which phylogenetic group includes all descendants of a common ancestor and only the
descendants of that ancestor? CORRECT ANS-monophyletic
evolution CORRECT ANS-changes in relative frequencies of alleles in a population's gene
pool over time
allele frequency CORRECT ANS-the proportion of an allele amongst all other alleles for a
particular gene/locus within a population
gene flow CORRECT ANS-the immigration or emigration of genetic material into or out of a
population resulting from the movement of fertile individuals or gametes. A mechanism of
microevolution
, Exam- Biology 1108- Exam 1(Chapters: 21-24, 27-28)
Questions and Answers
gene pool CORRECT ANS-the collection of all genes carried by the individuals in a
population
genetic drift CORRECT ANS-unpredictable fluctuations in allele frequencies from one
generation to the next
Heirdy-Weinberg Principle equation CORRECT ANS-p^2+2pq+q^2=1
Hardy Weinberg 5 assumptions CORRECT ANS-1. There can be no differences in the
survival and reproductive success of individuals
2. Populations can't be added or subtracted from by migration (closed population)
3. There can be no mutation
4. The population must be sufficiently large to prevent sampling errors
5. Individuals must mate at random
