Table entitled "genotypic-data.xlsx" presents the Genotypic data (genepop format) of the 875 individuals sampled in the course of the study. Spatial coordinates (Lambert II), sector of origin, year of sampling and sex are provided for each individual as follow: ind= unique code for each individual sex= sex of the sampled individual sector= sector where the individual was sampled (nine sectors in total) year= yar of sampling X_L2= X spatial coordinates (Lambert II) Y_L2= Y spatial coordinates (Lambert II) Ma54= individual genotype for locus Ma54 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma66= individual genotype for locus Ma66 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma68= individual genotype for locus Ma68 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma75= individual genotype for locus Ma75 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma81= individual genotype for locus Ma81 (genepop format, 3 digit per allele, 000000 represents missing genotypes) MSMM6= individual genotype for locus MSMM6 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma29= individual genotype for locus Ma29 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma25= individual genotype for locus Ma25 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma09= individual genotype for locus Ma09 (genepop format, 3 digit per allele, 000000 represents missing genotypes) Ma36= individual genotype for locus Ma36 (genepop format, 3 digit per allele, 000000 represents missing genotypes)
