| Abstract | In a previous study, the crossing time for the overdominant case in an infinite population was found to be saturated at a long sequence length in the diploid, coupled, discrete-time, mutation-selection model. The present study focused on the effect of a finite population size on the crossing time for the overdominant case. The dependence of the crossing time on the sequence length was simulated for a range of dominance parameters and selective advantages by switching on a diploid, asymmetric, bridged landscape from an initial state, a steady state in a diploid, bridged landscape. The boundary between the deterministic and the stochastic regions in the diploid, coupled, discrete-time, mutation-selection model was characterized using the same formula as that in the haploid, coupled, discrete-time, mutation-selection model. The crossing time in a finite population with various population sizes, dominance parameters and selective advantages began to deviate from the crossing time for an infinite population at a critical sequence length. The crossing time for a finite population in the stochastic region was found to be an exponentially increasing function of the sequence length, whose rate was unchanged, regardless of changes in the population size, dominance parameter and selective advantage with a fixed extension parameter. Therefore, the saturation of the crossing time at a long sequence length, which was observed for the overdominant case in an infinite population, could not be realized for a finite population. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
