    [Truncated abstract] For the convenience of the reader, detailed figures and tables have been enlarged and compiled in Appendix 2, at the end of this thesis. This thesis is presented as an approach to identify, annotate and detect genomic duplication and polymorphism within large genomic regions. To demonstrate this, I have used as a model, the genomic region known as the Regulators of Complement Activation (RCA). The RCA complex is located on the long arm of chromosome 1 at position 1q32 and is a reservoir of complement regulatory proteins. The genes of the RCA share many similarities implying that all have arisen through multiple complex duplication events. My analysis of this region in the following chapters demonstrates the complexity of this duplication and identifies the many functional units within the RCA. It was my aim at the beginning of these studies to demonstrate an approach that could define the Ancestral Haplotypes (AHs) of the RCA gene cluster. To do this, extensive genomic analysis was required and the ever-increasing availability of genomic sequence has made this thesis possible. Each of the chapters serves to address the following aims set out at the beginning of this thesis: 1. Further characterise the relationship between the genes (Complement Control proteins-CCPs) and domains of the Regulators of Complement Activation (RCA). 2. Identify and examine the duplicated elements within the RCA. - 6 - 3. Examine the effects of retroviruses and other insertions and deletions (indels) in generating the divergence of duplicated genes. 4. Investigate the applicability of the Genomic Matching Technique (GMT) to define AH within the region. 5. Examine association of AHs with CCP implicated diseases. 6. Determine the GMT applicability in non-human species
