Fast and efficient isolation of microsatellites from anonymous genomes a case study from the Antarctic benthos
Microsatellites are molecular markers with high resolving power and therefore a valuable tool for studying microevolutionary processes. However, identification of microsatellites and initial setup can be a labour intensive and time consuming task. We are applying microsatellites in a study aiming to...
