The Divergence of Halophilic Superoxide Dismutase Gene Sequences: Molecular Adaptation to High Saltld include selection (i) for altered structure or function within the encoded protein, (ii) for codon utilization as it relates to either efficiency or accuracy of mRNA translation, and (iii) for regulatory signals or secondary structure embedded in the DNA or mRNA sequence.

Mitochondrial Haplotype Frequencies in Oysters: Neutral Alternatives to Selection Models,t to the apparent lack of repair during replication. Because of its simple mode of inheritance, its ease of extraction and analysis and the extensive variation that can be observed in most animal populations, mitochondrial DNA (mtDNA) has been the focus of many population surveys since the late 1970s..,.

Using Maximum Likelihood to Infer Selection from Phylogenies, this structure will be rare. The frequency of different pairs of nucleotides at each site in the secondary structure is tabulated and the algorithm is used to obtain a maximum likelihood estimate of selection strength. A map of the potential strength of selection throughout the molecule is discussed.

Patterns of Polymorphism and Between Species Divergence in the Enzymes of Central Metabolism,gaster. In several labs elected enzymes have undergone a systematic analysis of the levels of nucleotide sequence polymorphism and interspecific divergence. Specifically in this lab the enzyme for glucose-6-phosphate dehydrogenase shows a dramatic deviation from the neutral expectation when levels o

Polymorphism and Divergence in Regions of Low Recombination in ,,etion polymorphism in different regions and in different species. While the general goal was a broad picture of variation, the next goal was to try to infer the mechanisms responsible for patterns of variation. For example, variation at loci on the sex chromosomes was found to be comparable to that
