Summary

The genetic diversity of most livestock species is reducing and it is not possible to preserve all livestock breeds. In order to preserve as much of the genetic diversity as possible we must first have a robust method of measuring the genetic differences between breeds. The analysis of microsatellite allele frequency is now the method of choice. Using sheep as an example, this paper describes the methods used for both microsatellite amplification and the analysis of the data once it has been collected.

Resumen

La diversidad genética de muchas especies ganaderas ha quedado muy reducida y no es posible preservar todas las razas. Para poder preservar el mayor número posible de razas, debemos, en primer lugar, poseer un método riguroso de medida de las diferencias genéticas existentes entre razas. El análisis de la frecuencia alálica de microsatélites es hoy en día un método importante. Tomando como ejemplo los ovinos, este artéculo describe los métodos utilizados para la amplificacion de microsatélites y el análisis de datos una vez recogidos.
