Twin-to-twin transfusion syndrome
What environmental factors can influence both monozygotic and dizygotic twins?
Mother's age, weight, and lifestyle choices
In terms of appearance and health outcomes, what may contribute to differences between monozygotic twins?
Environmental factors and genetic mutations
How do dizygotic twins develop compared to monozygotic twins?
From two separate eggs fertilized by two different sperm
What is the difference in the genetic material shared by monozygotic and dizygotic twins?
~50%
How do monozygotic twins develop from a genetic standpoint?
~50% shared genetic material due to single fertilization
Which factor may not necessarily contribute to differences in appearance between monozygotic twins?
