(a) Difference between a haploid and a diploid cell; definition and use of linkage to map chromosomes. (b) Description and justification of the design of a model of DNA. (c) Graph of data; definition of polygenic inheritance; comparison with Mendel's pattern of inheritance. (d) Comparison between selective breeding and gene cloning.
(a) Construct a table identifying effects of mutations. (b) Draw diagrams to show similarities and differences between chromosomes in the diploid cell and a haploid cell resulting from meiosis. (c) Predict ratios of phenotypes from a pedigree for linked and non-linked genes. (d) Explain how data can be collected to identify relative position of linked genes. Reasons why human genome project could not be achieved using linkage maps. (e) Evaluate how understanding of gene cloning and gene cascades has led to new applications for technologies.
