Gene Mapping and Disease Gene Identification
... Linkage analysis is a method that is used to decide if two loci or a loci and a disease gene are linked : 1. Ascertain whether the recombination fraction theta between two loci deviates significantly from 0.5. 2. If theta is different from 0.5, we need to make the best estimate of theta, since this ...

Q&A: Evolutionary capacitance Open Access Joanna Masel

The phenotypes of mutants such as gene knockouts are more variable than the phenotypes of the wild type [26], but this does not necessarily reflect mutational robustness. It does demonstrate the high robustness provided ...
