Question

Adoption studies focusing on the heritability of traits have

Answer 1

Adoption studies have focused on whether traits have a genetic basis, revealing that heritability is significant for various traits according to conclusions drawn from the Minnesota Study of Twins Reared Apart.

Step-by-step explanation:

Adoption studies focusing on the heritability of traits have primarily investigated c. whether traits have a genetic basis. Such studies, including the prominent Minnesota Study of Twins Reared Apart, have contributed significantly to our understanding of the genetic basis for personality and other traits. By comparing identical and fraternal twins raised together and separately, researchers deduced that heritability plays a significant role in traits like leadership, alienation, and fearfulness, amongst others. Heritability, in this context, refers to the proportion of variance among individuals in a population that is due to genetic differences. It is essential to understand that while heritability is a significant factor, environmental influences and epigenetic factors also shape an individual's phenotype.

Answer 2

The confirmation of what the twin studies had shown would be the effect of adoption studies focusing on heritability traits. In addition, these heritability traits are very essential to the study of biology and genetics since it basically determines how a specific kind of trait can affect the genetic variation in a population.
