Key Concepts and How to’s:


Evolution vs. Creation
Identify gametes
Create a continuum
Inheritance of traits
Passing of genes, alleles
Dominance vs. recessive
Punnett squares
Mendels’ laws – law of segregation, law of
independent assortment, law of dominance
 Chromosomal abnormalities
Prior knowledge:


Meiosis
Passing of genes
Reproduction
Generations


That a shared
vocabulary builds
understanding of
genetics
That Gregor Mendel
formed the basis for our
modern understanding
of genetics
That the genetics of
parents could result in a
variety but not unlimited
set of outcomes
Pedigrees will identify
generational inheritance
Evolution plays a role in
genetics
That understanding in
science develops and
shifts over time
That there are
mechanisms that control
inheritance and we can
make predictions based
on patterns
A number of factors
affect the prevalence of
genes and alleles in
populations

Pose questions about why and how offspring only inherit some
traits from their parents.
Discuss the historical development of Mendelian genetics,
including why Gregor Mendel is considered the “father of
genetics”.
Discuss the importance of probability in predicting the likelihood of
inheriting particular traits.
Discuss the historical development of scientific understanding of
Mendelian genetics, including the importance of statistical
analysis, probability, and significance.
Distinguish among patterns of inheritance (i.e., dominant and
recessive alleles, sex-linked traits, co-dominance, incomplete
dominance, and multiple alleles) of heritable traits.
Determine an organism’s phenotype from its genotype, and where
possible, its genotype from its phenotype.
Construct Punnett squares for monohybrid crosses using P1
genotypes (i.e., homozygous and heterozygous) to determine
genotypic and phenotypic frequencies for F1 and F2 generations.
Explore patterns of inheritance by interpreting pedigrees, including
own family tree.
Describe how gene flow, genetic drift and natural selection
influence the property of alleles within a population.
Recognize that scientists now understand chromosomes to be the
mechanism of Mendel’s laws
Investigate the importance of meiosis, including crossing-over, in
genetic variation in gametes and non-disjunction in creating
chromosomal abnormalities
Identify, using karyotypes, chromosomal abnormalities and how
these abnormalities may lead to chromosomal disorders such as
Klinefelter syndrome, Down syndrome and Turner syndrome
ESSENTIAL QUESTIONS
How did Gregor Mendel influence a modern understanding of genetics through his experiments and as a result of his
background?
Why can two perfectly healthy plants pass on a genetic disease?
Why are we better than we used to be, as humans?
Should insurance companies have access to your genetic information?
Before you select a life partner, should you check their genetics?
Why does our understanding of science keep changing? Isn’t a fact a fact?
How am I truly a product of my parents? Why am I not exactly half of one and half of another?
How do I make predictions about traits based on my understanding of genetics?
How do chromosomal abnormalities lead to chromosomal disorders?
