* In 1992, David Houle showed that measures of additive genetic variation standardized by the trait mean, CVA (the coefficient of additive genetic variation) and its square (IA), are suitable measures of evolvability*. CVA has been used widely to compare patterns of genetic variation. However, the use of CVAs for comparative purposes relies critically on the correct calculation of this parameter. As shown in the picture below, by calculating the formula, we got a sample correlation coefficient of 0.87. So, there is a strong relationship between the two values. A Correlation of 1.
