Twin Studies A twin is one of two children produced in the same pregnancy. Twins can either be identical (monozygotic) which means that they develop from one zygote that splits and forms two embryos‚ or they can be fraternal (dizygotic) which means that they develop from two separate eggs that are fertilized by two different sperms. Identical twins do have the same DNA‚ but they can be expressed in a different way. The environment the twins are exposed to determines the fine physical characteristics

vertical axis of the egg. Deuterostomes are further characterized by indeterminate cleavage‚ which means that each cell produced by early cleavage divisions retains the capacity to develop into a complete embryo. Indeterminate cleavage of the human zygote allows identical twins to be possible. In a protostome‚ as the archenteron forms‚ solid masses of mesoderm split to form the coelomic cavities‚ or schizocoelous development. In deuterostomes‚ the development of body cavities‚ or enterocoelous‚ happens
