ESSENTIAL QUESTION
S:

How are traits p
assed from parent to offspring?

What methods and models are used by biologists and geneticists to predict inheritance patterns?

How do
inheritance patterns
, environmental factors, and personal life choices

affect

the expression
traits?

SC.7.L.16.1

Underst
and and explain that every organism requires a set of instructions that specifies its traits, that this
hereditary information (DNA) contains genes located in the chromosomes of each cell, and that heredity is the
passage of these instructions from one gen
eration to another.

High

SC.7.L.16.2

Determine the probabilities for genotype and phenotype combinations using Punnett Squares and
pedigrees.

Moderate

SC.7.L.16.4

Recognize and explore the impact of biotechnology (cloning, genetic engineering, artificial s
election) on
the individual, society and the environment.

High

SC.912.L.16.2

Discuss observed inheritance patterns caused by various modes of inheritance, including dominant,
recessive, codominant, sex
-
linked, polygenic, and multiple alleles.

High



Be able to
define and
distinguish between

the following pairs of terms:

gene
s/
alleles;
dominant/recessive;
homozygous/heterozygous; genotype/phenotype
; monohybrid/dihybrid; incomplete dominance/codominance
;

multiple alleles/polygenic traits;
autosomal/sex
-
linked
.



Be able to identify the possible gamete combinations for each parent in a genetic cross (especially as this
applies to dihybrid crosses).



Be able to use a punnett square to predict the genotypes and phenotypes of offspring of both monohybrid

and
dihybrid crosses. If given the genotypes of offspring, be able to give the genotypes of parents.



Be able to interpret and correctly use the following terms as applicable to describe genotypes and phenotypes:
homozygous dominant, heterozygous, hom
ozygous recessive, pure
-
breeding, hybrid, carrier.



Be able to
determine and
use genotypic and phenotypic ratios to describe, predict and compare inheritance
patterns. Be familiar with the types of genetic crosses that produce the following ratios: 3:1,
1:2:1, 9:3:3:1.



Be able to read a family pedigree to figure out probable genotypes of family members (for example, whether a
family member is likely to be a carrier). Recognize what the squares, circles, and colored symbols represent.



Be able use the

labels

P
1
, F
1

and F
2

to identify generations in genetic crosses.



Be able to give examples of both recessive and dominant genetic disorders seen in humans.



Be able to describe in detail the method
s

used by Mendel to establish whether a trait was domi
nant or recessive
.
Describe the predictable phenotypes one would expect

in the F
1

and F
2

generations that would help with this
determination
.



Be able to recognize and distinguish between typical Mendelian inheritance patterns (dominant/recessive) and
inheritance patterns associated with incomplete dominance and codominance.



Be able explain the genetic basis for phenotypes seen in traits showing incomplete dominance and co
-
dominance.



Be able to describe how the sex chromosomes influence gender det
ermination in humans.



Be able to explain how the inheritance of sex
-
linked traits is different from that of
autosomal
tra
its.



Be able to predict the genotypes and phenotypes of
offspring when the inheritance pattern for a trait is
sex
-
linked
, as well as
determine the genotypes and phenotypes of parents
based on the phenotypes of offspring
.



Be able to
differentiate between and predict inheritance patterns for

traits determined by multiple alleles (like
blood type) and
p
olygenic traits (like

feline
coat
c
olors and patterns).



Be able to e
xplain why genetic
mutations

that arise in somatic cells
can give rise to genetic disorders that
are
not heritable.



Be able to e
xplain why
it is possible for an individual to develop a genetic disorder

even
when

there is
no
previous

family history of
the

disease.



Be able to differentiate between genetic engineering and

artificial selection
. Be able to give specific examples
of how
each of these
practices have
been used to genetically modify

crops and livestock
. Describe some of the
potential positive and negative impacts that GMOs can have on human health and the environment.





















Distinguish between the law of Segregation and the law of Independent Assortment. Be able

to explain them using your
own words.

Be able to distinguish between a monohybrid cross and a dihybrid cross. Which demonstrates the law of segregation?
Which demonstrates the law of independent assortment?
