Classical Genetics and Environmental Influences Objectives
BIG IDEA #3: LIVING SYSTEMS STORE, RETRIEVE, TRANSMIT AND RESPOND TO INFORMATION ESSENTIAL TO LIFE PROCESSES.
Enduring understanding 3.A: Heritable information provides for continuity of life.
Essential knowledge 3.A.2: In eukaryotes, heritable information is passed to the next generation via processes that include the cell cycle and mitosis or meiosis plus fertilization.
LO 3.11 The student is able to evaluate evidence provided by data sets
to support the claim that heritable information is passed from
one generation to another
Essential knowledge 3.A.3: The chromosomal basis of inheritance provides
an understanding of the pattern of passage
(transmission) of genes from parent to offspring.
LO 3.12 The student is able to construct a representation that connects
the process of meiosis to the passage of traits from parent to offspring.
LO 3.13 The student is able to pose questions about ethical, social or medical
issues surrounding human genetic disorders.
LO 3.14 The student is able to apply mathematical routines to determine
Mendelian patterns of inheritance provided by data sets.
Essential knowledge 3.A.4: The inheritance pattern of many traits cannot
be explained by simple Mendelian genetics.
LO 3.15 The student is able to explain deviations from Mendel’s model of
the inheritance of traits.
LO 3.16 The student is able to explain how the inheritance patterns of
many traits cannot be accounted for by Mendelian genetics.
LO 3.17 The student is able to describe representations of an
appropriate example of inheritance patterns that cannot be explained
by Mendel’s model of the inheritance of traits.
Big Idea 4: Biological systems interact, and these systems and
their interactions possess complex properties
Enduring understanding 4.C: Naturally occurring diversity among and between components within biological systems affects interactions with the environment.
Essential knowledge 4.C.2: Environmental factors influence the expression of the genotype in an organism.
LO 4.23 The student is able to construct explanations of the influence of
environmental factors on the phenotype of an organism.
LO 4.24 The student is able to predict the effects of a change in
an environmental factor on the genotypic expression of the phenotype.
Classical Genetics and Environmental Influences Learning Goals
Upon the completion of this unit the student will be able to:
1. list several features of Mendel's methods that contributed to his success.
2. list and explain Mendel's laws of heredity
3. use a Punnett square to predict the results of a monohybrid cross and state the
phenotypic and genotypic ratios of the F2 generation.
4. distinguish between genotype and phenotype; heterozygous and homozygous;
dominant and recessive.
5. explain how a testcross can be used to determine if a dominant phenotype is
homozygous or heterozygous.
6. state Mendel's law of independent assortment.
7. use a Punnett square to predict the results of a dihybrid cross and state
the phenotypic and genotypic ratios of the F2 generation.
8. using the laws of probability, predict the results of dihybrid and
9. state several; examples of incomplete dominance and explain this it is
not evidence for the blending theory of inheritance.
10. explain how the phenotypic expression of the heterozygote is affected
by complete dominance, incomplete dominance and codominance.
11. describe the inheritance of the ABO blood system and explain why the IA
and IB alleles are said to be codominant.
12. describe a simple model for polygenic inheritance, and explain why
most polygenic characters are described in quantitative terms.
13. describe how environmental conditions can influence the phenotypic
expression of a character.
14. given a simple family pedigree, deduce the genotypes for some of the
15. describe the inheritance of sickle cell disease.
16. explain how a lethal recessive gene can be maintained in a population.
17. explain why consanguinity increases the probability of homozygosity
18. explain why lethal dominant genes are much more rare than lethal
19. give an example of a late-acting lethal dominant in humans and explain
how it can escape elimination.
20. describe sex determination in humans.
21. describe the inheritance of a sex-linked gene such as color-blindness
22. explain why a recessive sex-linked gene is always expressed in human males.
23. explain the difference between deletion, translocation, and inversion mutations.
24. explain why cytoplasmic genes are not inherited in a Mendelian fashion.
25. list and discuss some examples of environmental influences on phenotype.
Students who demonstrate understanding can:
HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
Common Core State Standards Connections:
