The number of sets of twins the researches studied would be dependant on the tests they were performing. Generally, researchers will gather between 5 and 10 sets of twins for research.
environment
A twin study is a research method that involves studying identical or fraternal twins to explore the influences of genes and environment on traits or behaviors. By comparing similarities between twins raised in different environments, researchers can gain insight into the role of genetics in various aspects of human development.

Influence the people in the study
A psychologist would conduct a twin study to determine the heritability of a trait. By comparing the similarities between identical twins (who share 100% of their genes) with fraternal twins (who share 50% of their genes), researchers can estimate the genetic contribution to the trait.
Scieneces is the study of scienese twins, therefore, a study on scienese would be about scienese twins.
Yes, identical twins were used in the Human Genome Project to study genetic variation and heritability. By comparing the genomes of identical twins, researchers could identify genetic differences and understand how genes contribute to traits and diseases.
observational study
Identical twins are helpful to researchers studying the contribution of genetics and environment to behavior. Since identical twins share 100% of their genetic material, any differences in their behavior can be attributed to environmental factors. Comparing identical twins raised in different environments can help tease out the influence of genetics versus environment on behavior.
