Learning Outcomes / Ngā Whāinga Ako
- Understand the relationship between cells, nuclei, chromosomes, genes, alleles and DNA.
- Understand the role DNA plays in carrying instructions to the next generation and determining phenotype.
- Understand the structure of DNA (double helix, nucleotide, sugar, phosphate, base, and the base pairing rule).
- Understand that DNA contains the code for making proteins, and proteins are the building blocks for most of your body.
- Understand variation in terms of it being continuous or not continuous.
- Know and understand mitosis.
- Why and where it occurs.
- What happens to chromosome number and why.
- The significance of the number of cells produced.
- Understand the advantages and disadvantages of asexual reproduction in terms of producing offspring that are genetically identical (clones).
- Know and understand meiosis.
- Why and where it occurs.
- What happens to chromosome number and why.
- The significance of the number of cells produced.
- Understand how sexual reproduction produces new combinations of alleles.
- Compare and contrast mitosis and meiosis.
- Understand the importance of mutations in population variation and the importance of variation in a population to survive in a changing environment.
- Understand and use the terms “genotype and phenotype”, “homozygous and heterozygous” and “dominant and recessive”.
- Know how to carry out genetic crosses using punnet squares and determine genotypic and phenotypic ratios.
- Know how to use pedigree charts to determine genotype and phenotype.
- Understand how to use a ‘test cross’.
