Maternal-zygotic gene conflict over sex determination: effects of inbreeding.
There is growing evidence that sex determination in a wide range of organisms is determined by interactions between maternal-effect genes and zygotically expressing genes. Maternal-effect genes typically produce products (e.g., mRNA or proteins) that are placed into the egg during oogenesis and therefore depend upon maternal genotype. Here it is shown that maternal-effect and zygotic genes are ...
متن کاملSelection, Maternal Effects and Inbreeding in Reindeer Husbandry
Rönnegård, L. 2003. Selection, Maternal Effects and Inbreeding in Reindeer Husbandry. Doctor’s dissertation. ISSN 1401-6249. ISBN 91-576-6400-5. In extensive grazing systems where several owners’ flocks are allowed to mix, selection strategies will also interact, due to gene flow between flocks. The aim of the thesis was to analyse breeding schemes in terms of genetic gain and rate of inbreedin...
متن کاملInbreeding Effects upon Growth and Maternal Ability in Laboratory Mice.
The effects of systematically increasing levels of inbreeding upon growth and postnatal maternal ability were determined in laboratory mice by utilizing the reciprocal crossfostering technique. Two experiments were conducted. The first included postnatal dams which were inbred 0, 12, 25 and 38% while corresponding levels in the litter were 0, 22, 38 and 50%, respectively. The second experiment ...
متن کاملEvidence for inbreeding depression in a species with limited opportunity for maternal effects
It is often assumed that mating with close relatives reduces offspring fitness. In such cases, reduced offspring fitness may arise from inbreeding depression (i.e., genetic effects of elevated homozygosity) or from post-mating maternal investment. This can be due to a reduction in female investment after mating with genetically incompatible males ("differential allocation") or compensation for ...
متن کاملInbreeding, maternal care and genomic imprinting.
Inactivation of expression of the paternal allele at two maternally silent imprinted loci has recently been reported to diminish the quality of care that female mice lavish on their offspring. This suggests that there can be disagreement between the maternally and paternally derived genomes of mothers over how much care for offspring is appropriate, with the paternally derived genome favoring g...
