Inquiry question: How does reproduction ensure the continuity of a species?


      explain the mechanisms of reproduction that ensure the continuity of a species, by analysing sexual and asexual methods of reproduction in a variety of organisms, including but not limited to:

      animals: advantages of external and internal fertilisation

      plants: asexual and sexual reproduction

      fungi: budding, spores

      bacteria: binary fission

      protists: binary fission, budding

      analyse the features of fertilisation, implantation and hormonal control of pregnancy and birth in mammals

      evaluate the impact of scientific knowledge on the manipulation of plant and animal reproduction in agriculture    Review 

Cell Replication

Inquiry question: How important is it for genetic material to be replicated exactly?


      model the processes involved in cell replication, including but not limited to:

      mitosis and meiosis

      DNA replication using the Watson and Crick DNA model, including nucleotide composition, pairing and bonding

      assess the effect of the cell replication processes on the continuity of species                                                             

 DNA and Polypeptide Synthesis

Inquiry question: Why is polypeptide synthesis important?


      construct appropriate representations to model and compare the forms in which DNA exists in eukaryotes and prokaryotes

      model the process of polypeptide synthesis, including:

      transcription and translation

      in transcription and translation tRNAassessing the importance of mRNA and

      analysing the function and importance of polypeptide synthesis

      assessing how genes and environment affect phenotypic expression  

      investigate the structure and function of proteins in living things                                             Review

Genetic Variation

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


      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

      Punnett Squares constructing and interpreting information and data from pedigrees and

      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)     

Inheritance Patterns in a Population

Inquiry question: Can population genetic patterns be predicted with any accuracy?


      investigate the use of technologies to determine inheritance patterns in a population using, for example:

-          DNA sequencing and profiling

      for example:   investigate the use of data analysis from a large-scale collaborative project to identify trends, patterns and relationships,

-         the use of population genetics data in conservation management

-         population genetics studies used to determine the inheritance of a disease or disorder            

-          population genetics relating to human evolution                                                                 Review
