heritability was published in 2009 in the International Journal of Obesity. This study uses data from the "FinnTwin16" study in which nearly all twins born in Finland from 1975-79 are being tracked for many phenotypes. The table below reports correlation coefficients (rmz and dmz) separately for male and female twin pairs at about 30 years of age for 3 traits: BMI, waist circumference, and level of physical activity (the study investigated the relationships between these traits). Calculate H² for each trait and sex using the strategy discussed in Video 4.4. Match the your values with the appropriate trait and sex. Number of pairs BMI Waist circumference Physical activity Female BMI 0.77 0.71 0.55 Female physical activity Male BMI Female waist circumference Male physical activity Male waist circumference Female MZ 414 0.79 0.54 0.55 Male MZ 282 0.36 0.35 0.24 Female DZ 353 0.31 0.26 0.30 Male DZ 309
