Stars: **1/2
This book was confusing. It alternated between using the terms identical and fraternal and Monozygotic and Dizygotic. The first 4 or so chapters were not written well. They were boring to read. Most of it was large words that most people wouldn’t know. Interesting case studies were lost in statistical percentages that were confusing and almost impossible to understand. There had to be a better way to get the statistics across. Overall I wouldn’t recommend this book unless you were a researcher studying twins.
