BIO 1500 chapter 15
1. : changes in allele frequency in a population over time
: evolution of whole species over long periods of time: Mi-
croevolution, Macroevolution
2. : process by which one species splits into two or more
species
- Forms a conceptual bridge between and
.
-The accumulation of microevolutionary changes over a long period of time to
the point that the population is from other populations, and is
considered a distinct species: Speciation, microevolution, macroevolution, unique
,3. What is the biological species concept?: group of populations whose members have the potential
to interbreed in nature and produce viable, fertile offspring; do not breed successfully with members of other such
groups
4. between populations holds a species together genetical-
ly: Gene flow
5. The closer the relationship of two organisms, the more DNA they have in
common (TRUE OR FALSE): TRUE
6. The biological species concept emphasizes absence of
between different species: gene flow
7. are the offspring that result from a mating between different
species.: Hybrids
8. gene flow can occur between morphologically and ecologically distinct
, species (TRUE OR FALSE): TRUE
9. Other species concepts emphasize the within a species rather than
the separateness of different species: unity
10. applies to sexually reproducing species
It emphasizes
can be misleading in suggesting ability or inability to
mate.: BSC, reproductive isolation, Appearance
