You are interested in calculating the concordance for a trait of interest. You look at a total of 500 pairs of twins and find that of the 500 pairs, 125 pairs have ONE twin with the trait of interest and 50 pairs have BOTH twins with the trait of interest. Given this information, estimate the concordance for the trait of interest.
