Chapters 11 & 14.1
Genetics and Inheritance
LS-C6. Explain that a unit of hereditary information is called a gene, and genes may occur in different
forms called alleles (e.g., gene for pea plant height has two alleles, tall and short).
LS-C8. Use the concepts of Mendelian and non-Mendelian genetics (e.g., segregation, independent
assortment, dominant and recessive traits, sex-linked traits and jumping genes) to explain
inheritance.
We will be studying many things in the genetics unit, which covers parts of
chapters 11 (sections 1, 2 & 3) and 14 (section 1):
 Monohybrid crosses (1 trait)
Complete (Simple ) dominance
 Incomplete dominance
Codominance
 Dihybrid crosses
Sex-linked traits
 Pedigrees
The assessment for this unit will be a paper and pencil test over genetics and
inheritance. It has multiple choice and diagrams. There will be some genetic
problems for you to interpret, solve and explain. There will be some pedigrees for you
to interpret, solve and explain. It will go in the 70% category. There will also be a
research project about a genetic disorder that will be explained on another sheet of
paper.

Summarize Mendel’s experiments (ch 11.1)
Distinguish between self-fertilization and cross-fertilization (ch 11.1)
Distinguish between dominant and recessive traits (ch 11.1)
Use the 2 laws of heredity to explain genetic results (ch 11.1)
Differentiate between a gene and an allele (ch 11.1)
Perform monohybrid crosses and give genotypic and phenotypic ratios for
complete dominance, incomplete dominance, codominance and sex-linked traits
(ch 11.2, 11.3 & 14.1)
From a genetic problem, be able to tell whether a trait shows complete
dominance, incomplete dominance, codominance or is sex-linked and
prove/explain your answer. (ch 11.2, 11.3 & 14.1)
Perform dihybrid crosses and give genotypic and phenotypic ratios (ch 11.2)
Differentiate between an autosome and a sex chromosome (ch 14.1)
Explain what complex character and polygenic inheritance have to do with gene
expression (ch 11.3)
Analyze pedigrees to see how genetic traits/disorders are inherited (ch 14.1)
Use a pedigree to predict the outcome of the next generation (ch 14.1)
Use a pedigree to see who has a trait and who is a carrier (ch 14.1)
Use a pedigree to determine whether a trait is autosomal, sex-linked, dominant
or recessive (ch 14.1)
