“…In other rodents, the number of alleles observed was lower, but the degree of polymorphism of the loci was similar to that of midday gerbils. In Niviventer confucianus , the mean number of alleles was 16.875, and the PIC ranged from 0.825 to 0.943, with a mean of 0.866 (Ye et al 2016); in Lasiopodomys brandtii , the mean number of alleles was 10.00, and the PIC ranged from 0.645 to 0.897, with a mean of 0.753 (Mou 2019); and in Rattus losea , the mean number of alleles was 12.62, and the PIC ranged from 0.738 to 0.877, with a mean of 0.829 (Tan et al 2018).…”

Social mating systems (e.g., monogamy, polygamy, or polyandry) are relatively stable behavioral strategies developed by environmental in animals, but the genetic imprint of a particular mating system is often incongruent with the social mating system due to extrapair matings. However, the genetics of mating systems remain little understood in rodents. In this study, we investigated the genetic signature of the mating system of 141 (63 females, 78 males) field-captured midday gerbils (Meriones meridianus)—a rodent species commonly found in the Minqin Desert in China—through microsatellite site analyses of genetic structure and relatedness. Seven pairs of highly polymorphic microsatellite loci were selected and were highly polymorphic, with the combined exclusion probability greater than 0.99. The parent pair paternity test by Cervus 3.0 software show that 11 mother–offspring and nine father–offspring relationships were identified in 2018, involving 26 individuals from 10 families. Similarly, 19 mother–offspring and 19 father–offspring relationships were identified in 2019, involving 48 individuals from 18 families. All three types of genetic mating structure were identified—monogamy (19 families), polyandry (4 families), and polygyny (5 families), providing evidence that the genetics underlying mating systems in this species are variable, can be incongruent with behavioral evidence for social mating systems, and could vary based on environmental cues, including degree of perceived or actual predation.
