Genetic Traits
| In the
fifth unit, Genetic Traits, students will know that
changes in the environment can be so drastic that some
individuals and even some species are unable to survive.
When given a list of traits and characteristics the
students will identify which ones were a result of
environmental influence and which ones were genetic.
Students will use gene combinations to cross
characteristics on a Punnett Square and show the
possible differences in offspring.
Critical Questions:
- What factors affect the survivability of a
species?
- How are genetic traits related to what we observe?
- How can we predict possible characteristics of an
offspring?

Identify that changes in
environmental conditions such as drought, intense heat,
reduction in oxygen and temperature drop can affect the survival
of individuals and of species.
Analyze how natural or human events may have contributed
to the extinction of some species. (8.11 A-B)

Distinguish between inherited
traits that result from interactions with the environment such
as environmental factors-rainfall, temperature and food supply
and those that are genetic. (8.11 B) T8 |
