Module 5 | Heredity

Content 4: Genetic variation

Lesson 1 | Homologous chromosomes, meiosis, variation and mutation

  • conduct practical investigations to predict variations in the genotype of offspring by modelling meiosis, including the crossing over of homologous chromosomes, fertilisation and mutations (ACSBL084)

Lesson 2 | Monohybrid crosses

  • model the formation of new combinations of genotypes produced during meiosis, including but not limited to:
    – interpreting examples of autosomal, sex-linkage, co-dominance, incomplete dominance and multiple alleles (ACSBL085)
    – constructing and interpreting information and data from pedigrees and Punnett squares

Lesson 3 | Monohybrid crosses and predicting outcomes using Mendelian ratios

  • collect, record and present data to represent frequencies of characteristics in a population, in order to identify trends, patterns, relationships and limitations in data, for example:
    – examining frequency data
    – analysing single nucleotide polymorphism (SNP)

Lesson 4 | Co-dominance, incomplete dominance, and multiple alleles and sex-linkage

  • model the formation of new combinations of genotypes produced during meiosis, including but not limited to:
    – interpreting examples of autosomal, sex-linkage, co-dominance, incomplete dominance and multiple alleles(ACSBL085)

Lesson 5 | Pedigree charts

  • model the formation of new combinations of genotypes produced during meiosis, including but not limited to:
    – constructing and interpreting information and data from pedigrees and Punnett squares

Lesson 6 | Frequency of characteristics in a population

  • collect, record and present data to represent frequencies of characteristics in a population, in order to identify trends, patterns, relationships and limitations in data, for example:
    – examining frequency data
    – analysing single nucleotide polymorphism (SNP)
