State that two identical homozygous individuals that breed together will be pure-breeding
Explain why observed ratios often differ from expected ratios, especially when there are small numbers of offspring
Use genetic diagrams, including Punnett squares, to predict the results of monohybrid crosses and calculate phenotypic ratios, limited to 1:1 and 3:1 ratios
Understand and use the terms: dominant, recessive, phenotype, genotype, homozygous and heterozygous
Define an allele as an alternative form of a gene
Describe inheritance as the transmission of genetic information from generation to generation
Describe that different sequences of amino acids give different shapes to protein molecules
Describe that the sequence of bases in a gene determines the sequence of amino acids needed to make a specific protein (knowledge of the details of nucleotide structure is not required)
Explain that DNA controls cell function by controlling the production of proteins, including enzymes
Define a gene as a length of DNA that codes for a protein
