Explain the difference between dizygotic and monozygotic twins.
What will be an ideal response?
Dizygotic (DZ) twins are also called fraternal twins. DZ twins are conceived when a woman releases more than one ovum and each is fertilized by a different sperm. Genetically, DZ twins are no more similar to each other than other siblings that are conceived and born separately. Monozygotic (MZ), or identical twins, originate from the same zygote. MZ twins occur when the zygote splits into two distinct separate but identical zygotes that develop into two infants. MZ twins share the same genotype, with identical instructions for all physical and psychological characteristics.
