In case of mammals, identical twins arise when an embryo is results from a single fertilized egg which divides into two independent embryos, leads to the production of two genetically identical individuals. Based on this information, the question is asked When can this occur from a genetic view point. Describe the genetic implications when two genetically distinct embryos are fused in a single individual. Introduction: From a genetic viewpoint, twins are two offsprings that are produced by the same pregnancy. According to zygosity, there are two types of twins-monozygotic or dizygotic. Monozygotic twins are developed from one embryo in which one embryo splits into two embryos, whereas dizygotic twins are developed from two different eggs that are fertilized by separate sperms.
