GGT2 – Graphical Genotypes Software Tutorial

Introduction

Graphical genotyping using software such as GGT2 allows breeders to visualize the genotype of individuals and populations. Creating graphical genotypes can help breeders identify desirable individuals based on their genotype. The tutorial teaches users how to download GGT2 software, install GGT2 software, import or enter genotypic and map data, sort data, and identify desired genotypes.

In the event that the slideshare tutorial does not work, the tutorial is also attached as a pdf at the bottom of the page.
