Study Notes
Somerville House Science Exam
- The exam is for Year 9 Science students.
- The exam is an in-class exam.
- The exam is worth 50 marks.
- The exam is on Unit 1: Biology.
- The exam is on Topic 1: Genetics and Patterns of inheritance.
- The exam lasts 70 minutes.
- The exam includes multiple choice questions and short answer questions.
Australian Curriculum Descriptors
- The exam assesses ACSSU 184, which covers the transmission of heritable characteristics from one generation to the next.
- Students will need to demonstrate an understanding of DNA as the blueprint for controlling the characteristics of organisms.
- Students will need to use models and diagrams to represent the relationship between DNA, genes, and chromosomes.
- Students will need to recognize that genetic information passed on to offspring is from both parents by meiosis and fertilization.
- Students will need to represent patterns of inheritance of a simple dominant / recessive characteristic through generations of a family.
- Students will need to predict simple ratios of offspring genotypes and phenotypes in dominant / recessive gene pairs (sex-linked = extension only).
- Students will need to describe mutations as changes in DNA or chromosomes and outline the factors that contribute to mutation.
Science as a Human Endeavor
- The exam may also assess aspects of Science as a Human Endeavor, but the specific details are not provided in the text.
Year 9 Science - Unit 1: Biology
- In-class exam focused on Genetics and Patterns of Inheritance
- Assessment objectives cover ACSSU 184: Transmission of heritable characteristics from one generation to the next involves DNA and genes
- Total marks: 50
Topics covered in assessment:
-
DNA as the blueprint for controlling the characteristics of organisms:
-
Key functions of DNA:
- Holds genetic information that determines traits
- Acts as a blueprint for an organism's development and functioning
- Passed on to offspring from both parents
-
Key functions of DNA:
-
Relationship between DNA, genes and chromosomes:
- Chromosomes: Long strands of DNA
- Genes: Specific segments of DNA located on chromosomes
- DNA: Contains the instructions for building and maintaining an organism
-
Role of meiosis and fertilisation in passing on genetic information:
- Meiosis: Cell division process to produce genetically unique gametes (sex cells)
- Fertilisation: Fusion of male and female gametes, combining DNA from both parents
-
Patterns of inheritance of a simple dominant/recessive characteristic:
- Dominant trait: One copy of the gene is enough for the trait to be expressed
- Recessive trait: The trait is only expressed if two copies of the gene are present
- Examples can be used to predict offspring genotypes and phenotypes
-
Mutations:
- Changes in DNA or chromosomes: Alterations in the genetic code
-
Factors contributing to mutations:
- Environmental factors
- Exposure to radiation
- Errors during DNA replication
