Unit Test Review
Test Date:___________
1. Know the VOCABULARY/CONCEPTS specific to this unit so far. Not all terms were
studied. Read over all of your notes, quizzes and assignments.
 Chapter 3 Key Terms – p.123
 Chapter 4 Key Terms – p.157
 Chapter 5 Key Terms – p. 187
2. This is a summary of main topics and questions that you can try. We have covered a lot
of information. Some of the questions listed you have already done. Focus on the things
that you need help with during class time. Extra help is available at lunch.
Topic
DNA and Mitosis,
asexual vs sexual
reproduction, cloning
Meiosis
Abnormal meiosis
(non-disjunction) and
Karyotype charts
Mendelian genetics
Incomplete dominance
and co-dominance
Blood Types
(co-dominance)
Multiple alleles
Sex-linked Inheritance
Pedigrees
Dihybrid Crosses
Genetic Disorders
Main Ideas
Know the basic structure and function of
DNA, cell cycle, stages of mitosis and all of
the terms that go with it (i.e. centriole,
spindle fibres, centromere, equatorial
plate…)
Know the stages of meiosis, be able to
compare mitosis and meiosis,
What is a karyotype chart and what
information can be obtained from one?
Know terms monosomy, trisomy
Pea plant experiments, monohybrid crosses,
punnett squares, phenotypes, genotypes, F1,
F2 ratios, % or fractions
Phenotypic ratios for F1 & F2 generations in
snapdragons & shorthorn cattle
Punnett squares for ABO blood types, blood
types also consist of multiple alleles
Dominance hierarchies for fruit flies
Reference
Notes, homework
questions from
handout 4.1 and
4.2, p.82-91
Hemophilia, colour-blindness, baldness (who
passes on the recessive allele?)
Generations (roman numerals), male/female
symbols, determining genotypes given a
pedigree (i.e. for hemophilia), How to use a
pedigree to determine if a disorder is
recessive or dominant
Two traits – Determine parent genotypes,
gametes, phenotypic ratios of offspring
