Understanding Twins and Multiple Births: A Comprehensive Guide

Explore the fascinating world of twins and multiple births, including monozygotic and dizygotic twins, blastocyst development, amnion and chorion formation, placenta types, and the phenomena of twinning. Learn about the separation of blastomeres and primitive streak in monozygotic twins, as well as the unique characteristics of monozygotic multiple births. Count the numbers of multiples such as triplets, quadruplets, pentaplets, hexaplets, septuplets, and octaplets!
