4.6.1.4 4.6.1.5 If the two alleles present are the same the person is homozygous for that trait, but if the alleles are different they are heterozygous. Most characteristics are a result of multiple genes interacting. Some disorders are inherited, eg polydactyly and cystic fibrosis. A Punnett square can be constructed to predict the outcome of a monohybrid cross. genotypes and phenotypes of the offspring. Describe the inherited disorders polydactyly and cystic fibrosis. Use genetic cross diagrams to explain inheritance and carriers. Make informed judgements about the economic, social and ethical issues concerning embryo screening. Discuss the use of genetic modification to treat genetic disorders (links with 4.6.1.4). HT: Construct Punnet squares and genetic crosses. Evaluate genetic modification to treat cystic fibrosis. Produce notes and complete genetic diagrams to explain how polydactyly and cystic fibrosis are inherited. Interpret genetic diagrams relating to these disorders. Role play – choices for parents of a cystic fibrosis sufferer who would like another child.
