Genotypes of bears from Slovenia

The dataset contains genotypes of 510 brown bears genotyped on 22 microsatellite loci. They were obtained by genotyping tissue samples of legally killed bears between 2003 and 2008. Genotype on locus G10H is unrealiable (genotyping problems), and locus Mu26 has null alleles. Both were excluded from analysis, and have some missing data. All genotypes are complete on all other loci. Additional information is the age data (determined by tooth cross-section), sex and the date of mortality. Columns in the table: sample - laboratory name of the sample; sex - sex of the animal (recorded by the field crew and rechecked by genotyping the SRY marker); date_killed - the date on which the animal was killed; born - year of birth, estimated using the age data; age_months - age of the animal in months, calculated from the age determined by tooth cross-section, Feb 1 as the birthday and the recorded date of death. Genotypes: alleles at each locus are recorded in two columns, e.g. Cxx20_1, Cxx20_2. Missing data at loci G10H and Mu26 are recorded as "NA".本数据集包含510头棕熊的基因型数据，所有个体均通过22个微卫星位点（microsatellite loci）完成基因分型。样本数据来源于2003至2008年间合法猎捕的棕熊组织样本的基因分型结果。其中G10H位点的基因型结果不可靠，存在基因分型误差；Mu26位点存在无效等位基因（null alleles），二者均已被排除在后续分析之外，且存在部分缺失数据。其余所有位点的基因型数据均完整无缺。数据集额外收录了三类补充信息：通过牙齿横截面测定的年龄数据、个体性别以及死亡日期。数据表各列的具体含义如下：sample：样本的实验室标识名称；sex：个体性别，由野外作业人员记录，并通过SRY标记（SRY marker）基因分型结果复核确认；date_killed：个体被猎捕的日期；born：通过年龄数据估算得到的个体出生年份；age_months：以每年2月1日作为个体生日，结合记录的死亡日期，由牙齿横截面测定的年龄换算得到的个体月龄。基因型数据中，每个位点的等位基因通过两列数据进行记录，例如Cxx20_1、Cxx20_2。G10H与Mu26位点的缺失数据以"NA"进行标注。
