With newfound enthusiasm, Rohan set out to apply these techniques to his own breeding program. He began by collecting data on various characteristics of his crops, such as plant height, leaf size, and yield. Using statistical software, he analyzed the data, searching for relationships between the different traits. The results were astonishing – Rohan discovered that certain combinations of traits were associated with significantly higher yields and improved disease resistance.

This partitions gene effects into metric traits: additive ( ), dominance ( ), and epistatic interactions like additive additive ( ), additive dominance ( ), and dominance dominance ( Multi-Trait Selection and Association Analysis Using statistical software, he analyzed the data, searching

If you are analyzing data based on the principles found in Jawahar R. Sharma's text, manual calculations are no longer necessary. You can implement these exact biometrical models using modern statistical software:
