Effect of Blood Group on Blood Lipids in Monozygotic Twins
THE total variance of any measurement made in a population of monozygotic twins can be divided into two parts: interpair variance and intrapair variance. Calculation of the interpair/intrapair F ratio is informative because if this statistic is significantly large it shows that genotype affects the...

Zusammenfassung: | THE total variance of any measurement made in a population of monozygotic twins can be divided into two parts: interpair variance and intrapair variance. Calculation of the interpair/intrapair
F
ratio is informative because if this statistic is significantly large it shows that genotype affects the measured variable. Monozygotic twins of the same pair share a common genotype, and so intrapair variance is caused only by environmental effects. These can be divided into two parts: short term effects and long term effects. |
