Strength 1.As specifc group of people, twins as the cohort subject can be more recognized by the twins, which is an advantage to attract large quantity of twin vulenteers.
2.Investigation of the correlation of heredity and environmental factor using the twin cohort has specific advantage that other population cohorts do not have and natural control is the primary advantage.
Weakness 1. The extreme dispersibility of twin in population makes the organization and administration of twin cohort difficult.
2. The cohor lacks stable funds and encourge mechanism.
