ESSENTIAL UNIT 3 (E03)
(Genetics)
Suggested Rubric
The following rubric may be used by the teacher to distinguish between ‘A’-level and
‘B’-level work in E03. TSW’s which do not lend themselves to ‘A’-level work do not
have suggestions.
Statement
TSW 1
Mendel
‘A’-level
Student is able to describe Mendel’s
experiments, evaluate their results and
explain their importance to the study of
genetics.
TSW 2
Alleles
TSW 3
Punnett squares
TSW 4
Patterns of
inheritance
TSW 5
inheritance
Student can use Punnett squares showing a
single trait to explain the difference
between genotype and phenotype and
explain how the squares can be used to
illustrate probability of inheritance of a
specific trait.
Student can describe and give examples
for four complex patterns of inheritance.
‘B’-level
Student is able to describe the results of
Mendel’s experiments and explain their
importance to the study of genetics.
Student can identify the role of alleles in
controlling the appearance and inheritance
of traits.
Student can use Punnett squares showing
a single trait to explain the difference
between genotype and phenotype.
Student can give examples of four
complex patterns of inheritance.
Students discuss inheritance as
combination of environmental and genetic
factors.
Student can describe how genes make up
DNA and DNA is folded to form
chromosomes and recognize that
chromosomes play a role in inheritance.
TSW 6
DNA, genes,
chromosomes
Student can describe the relationship
between DNA, genes and chromosomes
and how Sutton recognized their roles in
inheritance.
TSW 7
meiosis
Student can illustrate and relate the events
that occur during meiosis, comparing and
contrasting them with the steps of mitosis.
Student can relate the events that occur
during meiosis, comparing and contrasting
them with the steps of mitosis, using an
illustration as a guide.
TSW 8
Protein
synthesis and
RNA
In addition to B-level work, student can
give a detailed explanation of the process
of protein synthesis.
Student can describe protein as being
made of a combination of as many as 20
different amino acids and that tRNA and
mRNA work together to create proteins
with information using information
received from DNA in the nucleus.
Student can explain how human traits are
controlled in different ways and give one
example for each, recognizing that
multiple allele control means multiple
alleles exist, but an individual has only
two of those alleles.
Student can explain three different ways
genetic disorders can be inherited in
humans and list different methods for
diagnosing and treating them.
TSW 9
Human traits
TSW 11
Genetic
disorders
Student can explain at least four different
ways genetic disorders can be inherited in
humans and describe different methods for
diagnosing and treating them.
