Inquiry question: How can the genetic similarities and differences within and between species be
compared?

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).

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

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)
