1.9.1 Structure of DNA
Lesson Objectives:
DNA forms the foundation of all genetics. You should be able to: - Draw and label a strand of DNA - Explain where DNA and chromosomes are found - Describe the structure of DNA and chromosomes - Explain the difference between similarities and differences between DNA, Genes, and chromosomes Text Pages 7-10

1.9.2 DNA Replication
Lesson Objective:
Describe the key steps in DNA replication Text Page 11
|
|
1.9.3 DNA Translation
Lesson Objective:
Describe how DNA is translated into proteins and the significance of this process to cells and organisms. Text page 13
NOTE: DNA Transcription and Translation are not part of the level 1 standard but will help link the importance of DNA with gene expression.

1.9.4 Mitosis
Lesson Objective
Discuss and describe the key steps in Mitosis, especially what is happening to the DNA at each step. Text Pages 12
|
|
1.9.5 Meiosis
Lesson Objective:
Discuss and describe the key stages in Meiosis, especially noting what is happening to the DNA. Compare and contrast Mitosis vs Meiosis. Text Pages N/A: Meiosis will be revisited later in the unit.

1.9.6 Genes, Traits, Alleles
Lesson Objective:
There is a lot of important vocabulary for discussing genetics and heredity. Be ready to discuss, describe, explain, compare, contrast any of the vocabulary in this unit. Text Page 14

1.9.7 Sex Determination
Lesson Objective
Explain how sex is determined in mammals using X and Y chromosomes. Text Pages 22-23
|
|
1.9.8 Punnett Squares and Predicting Inheritance
Lesson Objective
- Use Punnett squares to predict offspring traits based on parent genotypes - Use Punnett squares to determine parent traits based on offspring phenotypes - Use Punnett squares to describe offspring genotype and phenotype ratios and predict the likelihood of specific traits Text Pages 24-34
|
|
1.9 Extension B: Advanced PunnetT squares
NOTE: These genetic cross scenarios are more complicated than you are expected to know at the level 1 standard but provide good extension and problem solving strategies.
|
|
1.9.9 Pedigrees
Lesson Objectives
- Use pedigree charts to follow family trees - Use pedigree charts and punnett squares to determine and explain links between parent/offspring genotypes/phenotypes Text Pages 36-40
Predicting Inheritance Chapter Review
Pages 43-47 |
|
1.9.10 Genetic Variation
Lesson Objectives
Describe genetic variation and discuss its significance Describe various types of variation Describe various sources of variation Text pages 49-52
|
|
1.9.11 Sexual vs Asexual Reproduction
Lesson Objective
Compare and contrast the pros and cons of sexual vs asexual reproduction including links to genetic variation. Text Pages 53, 56-57
|
|
1.9.12 Meiosis (again)
Lesson Objective
Explain how the mechanics of meiosis leads to two different types of genetic variation via independent assortment and crossing-over. Text Pages 54-55
|
|
1.9.13 Mutation
Lesson Objective
Discuss and compare mutations that occur in somatic vs sex cells. Make links and/or comparisons to genes, alleles, cancer, physical injury, sexual reproduction, and/or DNA. Also compare mutations that could be helpful, harmful, or have no effect Text Pages 58-59
|
|
1.9.14 Population Genetics and the importance of variation
Lesson Objective
Discuss how traits occur in populations. Discuss the role of 'gene frequency' in population genetics. Discuss the importance of genetic diversity. Text Pages 60-64
|
|
1.9.15 Cloning (Extension???)
Lesson Objective
Cloning is a special case of asexual reproduction that has various clinical benefits. Describe the standard process for making a clone and discuss the implications for the individual, and a population. Text Pages N/A
