I am working in the genetic diversity analysis of a plant species and have used RAPD and ISSR markers. After scoring the data in a binary matrix, I am trying to find the marker index of the primers. I need a software which can do the job easier for me. So does anyone has a information about a software which can help me find the Marker Index(MI) for a dominant marker system. I have searched for the software but all I got was a formula,which makes the calculation complicated.
