How many founders, how large a population?
Abstract The number of population founders and the size of the population are two important variables in determining how much gene diversity can be retained in a population. A model is developed to determine the most cost-effective balance of those two variables, based on comparing the marginal costs of increasing the number of founders vs. […]
Assimilation of new founders into existing captive populations
Abstract 10.1002/zoo.1430130210.abs When new founders are added to an existing captive population, it is useful to establish a target number of offspring from each of these new founders that will maximize the amount of gene diversity retained in the captive population. This article presents a method for calculating an optimal number of offspring that should […]
Use of animals with unknown ancestries in scientifically managed breeding programs
Abstract 10.1002/zoo.1430120203.abs Whether to incorporate animals with unknown ancestries as founders into scientifically managed captive breeding programs, can be a difficult decision. If the animals are offspring of known founders, their inclusion in the breeding program will result in an increased incidence of inbreeding in the captive population. If the animals are additional founders, excluding […]
