Chapter 12, Problem 20STP
Summary Introduction
To explain:
Types of twins needed for study, and the reason behind that.
Introduction:
Twins are the individuals that are simultaneously born from the same mother. Twins are of various types, monozygotic twins (identical twins) and dizygotic twins (fraternal twins). Monozygotic twins are formed when a fertilized egg splits into two and dizygotic twins are formed when first egg splits into two and then they get fertilized.
Expert Solution & Answer
Explanation of Solution
Identical twins help scientists to separate genetic contributions and environmental contributions. Identical twins have same genetic makeup. If a trait is inherited, both the twins will have it. The concordance rate determines the percentage of twins who express same traits. It is highest in identical twins. So, if a scientist wants to study about reading disability, then he must need identical twins.
