What is a marker for genetics

Genetic markers are used to identify different features in DNA sequence that can be used to differentiate between individuals in a population, or to classify individuals between different varieties or cultivars within a species.

The different features in the sequence can be used to identify if that particular region was inherited from the female or male parent.

By using this information we can build up a more complete picture of each individuals genotype at each marker.

This allows us to track the inheritance of different regions of the genome.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
