Exact Inbreeding Coefficients in Populations
A theory is given that allows inbreeding coefficients to be calculated exactly for populations with overlapping generations. Emphasis is placed on providing equations well suited for computer iteration. Both monoecious and dioecious populations are considered and family size is not restricted to being Poisson. One-locus and two-locus inbreeding coefficients are evaluated, although the reader ma...
متن کاملComputing Downwards Accumulations on Trees Quickly
Downwards accumulations on binary trees are essentially functions which pass information down a tree, from the root towards the leaves. Under certain conditions, a downwards accumulation is bothèecient' (computable in a functional style in parallel time proportional to the depth of the tree) and`manipulable' (enjoying a number of distributivity properties useful in program construction). In thi...
متن کاملThe effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding ...
متن کاملSpawning, copulation and inbreeding coefficients in marine invertebrates.
Patterns of population genetic variation have frequently been understood as consequences of life history covariates such as dispersal ability and breeding systems (e.g. selfing). For example, marine invertebrates show enormous variation in life history traits that are correlated with the extent of gene flow between populations and the magnitude of differentiation among populations at neutral ge...
متن کاملEstimating Allele Frequencies and Inbreeding Coefficients in K-Allele Models
Some of the methods of estimation of allele frequencies and inbreeding coefficients in a K-allele model are examined. A result that has long been assumed to be true is proved. That is, in the presence of inbreeding, the maximum likelihood estimators of the allele frequencies and of the inbreeding coefficient f do not in general equal their observed (or sample) values (except when K 1⁄4 2). A le...
