Discuss the methodological importance of MZA twins
What will be an ideal response?
Answer: MZA twins are monozygotic twins reared apart. This is an extremely important group of individuals for a variety of research projects including many focused on personality development. Monozygotic twins start off genetically identical as they are derived from one egg fertilized by one sperm that splits into two zygotes very early in development. If monozygotic twins are reared in the same family and school then there is the possibility that neither their genome nor their environment are much different. If, however, they are adopted into two different families then there is the possibility that their environments are different. If their genomes are very close to identical then any differences in personality may be attributed to environmental forces.
