Genetic Variation

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

Inquiry Question

Overview

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