Essential
Questions:
- Why do cells divide?
- How does one cell become two?
- How do cells pass along copies
of their genetic material?
- How is the cell cycle regulated?
- How do two parents create one
offspring? How do two cells
become one? AKA what is sexual reproduction?
- How is the genetic composition
of the offspring of sexual reproduction composed?
- How do parents pass along
genetic traits?
- What is meiosis? What is its purpose?
- What are the many ways in which
meiosis and sexual reproduction lead to genetic diversity?
- Who was Gregor Mendel and how
did his work lead to our better understanding genetics and the process
of inheritance?
- What rules govern the process of
trait inheritance?
- How are Mendel’s discoveries
supported by our understanding of DNA structure and function, and
meiosis?
- What variations on Mendel’s
themes do we know?
- What is the nature of sex chromosomes
and what implications does that have for genetics?
- What are linked genes?
- What happens when the process
goes wrong?

Objectives:
- Investigate why cells need to
divide.
- Illustrate the cell cycle and
define its elements.
- Differentiate between cell
division and nuclear division.
- Discuss how our understanding of
DNA structure, function, and replication relates to cell division.
- Compare and contrast asexual and
sexual reproduction as it relates to the inheritance of genetic material
and genetic diversity.
- Explain the importance of
meiosis and fertilization
- Describe in detail the events of
meiosis.
- Illustrate the processes of
meiosis, and fertilization
- Discuss how genetic variation
impacts the overall population.
- Describe in detail Mendel’s
contribution to our understanding of genetics in a historic context.
- Explain the concept of dominance
and how it led to our understanding of the particulate nature of genes.
- Define genotype and phenotype.
- Explain in detail the laws of
segregation and independent assortment.
- Illustrate how these laws can be
explained by the physical processes during meiosis.
- Employ the use of Punnet squares
to analyze genetic combinations and offspring probabilities.
- Explain a few simple laws of probability
that govern simple Mendelian genetics.
- Explore the various variations
on Mendels’s discoveries – incomplete dominance, co-dominance,
polygenics, multiple alleles, plieotropy.
- Employ punnets squares to
analyze these variations.
- Explain pedigrees.
- Use pedigree analysis to track
and predict the expression of a trait or the presence of a gene.
- Investigate Morgan’s experiments
on fruit flies and explain the concept of sex-linked traits.
- Differentiate between autosomes
and sex chromosomes.
- Investigate the effect of linked
genes on independent assortment.
- Explain how we can use
cross-over data to map the relative location of linked genes on a
chromosome.
- Discuss chromosomal mutations.
- Discuss how variations in
chromosome structure affect individuals - with specific examples.
- Describe variations in
chromosome number and the effects of these variations – use specific
examples.
