Exemplary Report: 5 pts.
|
An exemplary report will have the following
characteristics
- All crosses are diagramed both
phenotypically and genotypically with clear
symbols that reflect the hypothesized
inheritance pattern.
- After each cross the results are analyzed
and there is a clear statement of the students
current hypothesis.
- Predictions based on the hypothesis are made
for the each cross before doing the cross
and the crosses chosen are appropriate for
testing the current hypothesis.
- Student rejects all hypotheses not supported
by the evidence and proposes new hypotheses.
- There is a conclusion that correctly
explains the inheritance pattern for the trait,
with supporting evidence, or a conclusion that
clearly describes why all reasonable hypotheses
can not explain the results, with supporting
evidence.
- If all known hypotheses are inadequate,
student shows some creativity in coming up with
at least one alternative hypotheses to test.
- The report shows a clear understanding of
the genetics covered up to this point in class
that is applicable to this problem, is neat and
well organized, with no superfluous or
unexplained crosses.

Satisfactory Report: 4 pts.

A satisfactory report will have the following
characteristics
- All crosses are diagramed both
phenotypically and genotypically with clear
symbols that reflect the hypothesized
inheritance pattern.
- After each cross the results are analyzed
and there is a clear statement of the students
current hypothesis.
- Predictions based on the hypothesis are made
for the each cross before doing the cross
and the crosses chosen are appropriate for
testing the current hypothesis.
- There is a conclusion that correctly
explains the inheritance pattern for the trait,
with supporting evidence, or a conclusion that
clearly describes why all reasonable hypotheses
can not explain the results, with supporting
evidence.
- The report is not always clearly written and
has inappropriate crosses or crosses that are
not well explained, but does include the
appropriate crosses and does explain what is
going on.

Serious Flaws But Nearly Satisfactory: 3 pts.
|
A nearly satisfactory report will have the
following characteristics
- All crosses are diagramed both
phenotypically and genotypically with clear
symbols that reflect the hypothesized
inheritance pattern.
- Does not always have predictions for what
will happen in a cross and does not discuss the
results from all crosses.
- Has at least tested the most likely
hypotheses and shows a basic knowledge of the
appropriate genetics.
- Has a conclusion with supporting evidence
and has clearly tried to solve the problem, but
may not have a complete solution.

Begins, But Fails to complete Problem: 2 pts.
|
An incomplete report will have the following
characteristics
- All crosses are diagramed both
phenotypically and genotypically with clear
symbols that reflect the hypothesized
inheritance pattern.
- Can not make reasonable predictions of the
results of a cross and can not always tell
whether a cross supports or refutes a hypotheses
but does know what some of the hypotheses should
be.

Unable to Begin Effectively: 1 pt.
|
A poor report will have the following
characteristics
- Can not properly distinguish between
phenotype and genotype
- Can not diagram cross or make reasonable
predictions based on a Mendelian hypothesis.
