Polygyny is expected to erode genetic variability by reducing the diversity of genetic contribution of males to the next generation, although empirical evidence shows that genetic variability in polygynous populations is not lost as rapidly as expected. We used microsatellite markers to study the genetic variability transmitted by mothers and fathers to offspring during a reproductive season in wild populations of a polygynous mammal, the red deer. Contrary to expectations, we found that males… 
Males and Females Contribute Unequally to Offspring Genetic Diversity in the Polygynandrous Mating System of Wild Boar
TLDR
Estimating the contribution of males and females to genetic variation in the next generation in independent wild boar populations from the Iberian Peninsula and Hungary suggests new insights into how promiscuous mating systems can help maintain genetic variation.
Parents’ genetic dissimilarity and offspring sex in a polygynous mammal
TLDR
Red deer microsatellite genotypes were studied to hypothesized that when sexual selection produces sex‐specific selective scenarios, the relative benefits of additive genetic vs. dissimilarity may differ for sons and daughters, and found that parental lineages were more dissimilar in daughters than in sons.
Loss of Mhc and Neutral Variation in Peary Caribou: Genetic Drift Is Not Mitigated by Balancing Selection or Exacerbated by Mhc Allele Distributions
TLDR
It is observed that similar proportions of genetic variation were lost over time at each type of marker despite strong evidence for selection at Mhc genes, suggesting that microsatellites can be used to estimate genome-wide levels of variation, but also that adaptive potential is likely to be lost following population bottlenecks.
Low heterozygosity at microsatellite markers in Iberian red deer with small antlers.
TLDR
It is found that males with very small antlers had lower levels of heterozygosity than those with bigger antlers (significant effect in an analysis of variance, P = 0.011), with implications for red deer evolution and management.
Female‐biased dispersal under conditions of low male mating competition in a polygynous mammal
TLDR
The shift of the sex‐biased dispersal pattern along the gradient of mate competition highlights its condition‐dependence as well as the interaction between male and female dispersal in the evolution of sex‐ biased dispersal.
Prevalence of polygyny in a critically endangered marine turtle population
Population dynamics of a natural red deer population over 200 years detected via substantial changes of genetic variation
TLDR
It is demonstrated that government policy and hunting laws may have strong impacts on populations that can lead to unexpectedly rapid changes in the genetic constitution of a large mammal population.
GOOD GENES DRIVE FEMALE CHOICE FOR MATING PARTNERS IN THE LEK‐BREEDING EUROPEAN TREEFROG
TLDR
It is concluded that females are able to choose good partners under natural settings and obtain benefits from the good genes, rather than compatible genes, their offspring inherit, which is likely to reduce effective population sizes below values previously estimated.
Population structure, habitat features and genetic structure of managed red deer populations
TLDR
Red deer populations in Spain are studied to discuss the possible connection between resource availability and genetic structure, and to find any population or environmental variable related to genetic differentiation within metapopulations.

Genetic similarity, breeding distribution range and sexual selection
TLDR
It is suggested that breeding distribution range, population size and intensity of sexual selection are important predictors of levels of genetic variability in extant populations.
GENETIC CONSEQUENCES OF POLYGYNY AND SOCIAL STRUCTURE IN AN INDIAN FRUIT BAT, CYNOPTERUS SPHINX. II. VARIANCE IN MALE MATING SUCCESS AND EFFECTIVE POPULATION SIZE
TLDR
This hypothesis that polygynous mating results in significantly reduced Ne in an age-structured population of a harem-forming fruit bat, Cynopterus sphinx, in western India is tested.
Unexpected heterozygosity in an island mouflon population founded by a single pair of individuals
TLDR
This study analysed changes in heterozygosity over time in an insular mouflon population founded by two individuals in 1957 and located on one of the most isolated locations in the world: the Kerguelen Sub-Antarctic archipelago.

Microsatellites reveal heterosis in red deer
TLDR
It is concluded that in the deer population fitness measures expressed early in life do not show evidence of inbreeding depression, but they do showEvidence of heterosis, possibly as a result of population mixing.
Inbreeding depression influences lifetime breeding success in a wild population of red deer (Cervus elaphus)
TLDR
It is shown that heterozygosity is positively associated with male and female adult LBS in a wild population of red deer on the Isle of Rum, Scotland, the first time that inbreeding depression and/or heterosis have been detected for a trait highly correlated with overall fitness in both sexes in aWild population.
Selection against inbred song sparrows during a natural population bottleneck
TLDR
It is reported that song sparrows that survived a severe population bottleneck were a non-random subset of the pre-crash population with respect to inbreeding, and that natural selection favoured outbred individuals, suggesting that inbreeding depression was expressed in the face of an environmental challenge.
African buffalo maintain high genetic diversity in the major histocompatibility complex in spite of historically known population bottlenecks
TLDR
Polymorphism in the major histocompatibity complex (MHC) DRB3 gene was probed by means of restriction analysis of the sequence encoding the peptide‐binding region, and nucleotide substitution patterns agreed with a positive selection acting on this fitness‐relevant locus.
How cuckoldry can decrease the opportunity for sexual selection: Data and theory from a genetic parentage analysis of the sand goby, Pomatoschistus minutus
TLDR
A simple mathematical model is developed showing that sneaking in this polygynous sand goby population almost certainly decreases the opportunity for sexual selection, an outcome that contrasts with the usual effects of cuckoldry in socially monogamous animals.
Sexual selection and the evolution of evolvability
TLDR
It is shown that sexual selection can have an effect on the rate of mutation, and a choice of two male subjects was sufficient for there to be a twofold increase in the mutation rate as opposed to a decrease found under random mating.
