Vedclass · Answer

(A) The term 'twin' refers to two offspring produced in the same pregnancy.Twins can be classified into two main types:$1$. Monozygotic (Identical) Twins: These are developed from a single zygote that splits into two embryos after fertilization.$2$. Dizygotic (Fraternal) Twins: These are developed from two different zygotes,formed by the fertilization of two separate ova by two separate sperm.Since the question asks for a general definition of a twin,and option $A$ describes the formation of identical twins,it is the most specific biological definition related to zygotic development.
