Abstract

Here we characterize nine microsatellite loci for Thoropa taophora collected from a coastal and an island population in southeastern Brazil. The number of alleles per locus ranged from three to 11 for the coastal population and from two to eight for the island population. Observed heterozygosities ranged from 0.308 to 0.778 for the coastal population and from zero to 0.737 for the island population. One locus did not conform to Hardy-Weinberg expectations on the coast, while two were in disequilibrium on the island. These markers are currently being used to examine genetic differentiation and patterns of dispersal in T. taophora.

摘要

本研究从巴西东南部的沿海和岛屿地区采集了九种 Taophora thoropa 微卫星位点,并对其进行了特征描述。沿海种群的每个位点等位基因数范围为 3 到 11,而岛屿种群的等位基因数范围为 2 到 8。沿海种群的观测杂合度范围为 0.308 到 0.778,而岛屿种群的观测杂合度范围为零到 0.737。一个位点在沿海地区不符合 Hardy-Weinberg 预期,而两个位点在岛屿上处于不平衡状态。这些标记物目前正在用于研究 Taophora thoropa 的遗传分化和扩散模式。
