A method of estimating the number of histocompatibility loci in a sib-mating mouse population.
h”mno1ogic and genetic bases of histocompatibility are well established. TFFe rejection of an incompatible graft is due to an immunologic reaction of the host against the graft of the donor which contains one or more antigens lacking in the tissues of the host. The antigens involved in transplantation immunity are known to be genetically determined. These determinants, defined as histocompatibi...
متن کاملKin selection is implicated in partial sib-mating populations with constant viability differences before mating.
The change in the frequency of a rare mutant allele under constant sex-differentiated viability selection in an infinite, partial full-sib mating population is studied. The diplo-diploid and haplo-diploid polygynous models are considered with a Poisson distribution for the number of offspring produced by every mated female. Reproduction is followed by weak selection among the offspring and then...
متن کاملFungal mating-type loci
Fungi form one of the most ubiquitous and successful kingdoms of life on Earth. There are more than 100,000 known species of fungi, divided into four phyla — ascomycetes, basidiomycetes, zygomycetes and chytrids — and these have populated a vast array of biological niches, including those that are pathogens of animals (including humans and insects), plants and even other microorganisms. The mor...
متن کاملSib-mating in the ant Plagiolepis pygmaea: adaptative inbreeding?
Multiple functional queens in a colony (polygyny) and multiple mating by queens (polyandry) in social insects challenge kin selection, because they dilute inclusive fitness benefits from helping. Colonies of the ant Plagiolepis pygmaea brash contain several hundreds of multiply mated queens. Yet, within-colony relatedness remains unexpectedly high. This stems from low male dispersal, extensive ...
متن کاملSib mating without inbreeding in the longhorn crazy ant.
Sib matings increase homozygosity and, hence, the frequency of detrimental phenotypes caused by recessive deleterious alleles. However, many species have evolved adaptations that prevent the genetic costs associated with inbreeding. We discovered that the highly invasive longhorn crazy ant, Paratrechina longicornis, has evolved an unusual mode of reproduction whereby sib mating does not result ...
