Answers
▪ Speciation :-
It is an event that splits a population by evolutionary means into two independent species which cannot reproduce among themselves. Speciation occurs when a population exhibits a continuous change due to changes in the environment. These unit changes get accumulated over a period of time in a section of population which slowly alter the individual's structure and functions to give rise to a new species. There are two types of speciation namely allopatric speciation and sympathatic speciation.
I hope its help for you!
Mere bhi semester exam me aaya tha same question.
Answer:
in multicellular organisms , sexual reproduction takes place which causes variations in them , when these variations are accumulated in that species then after million of years new species are formed . this process is called speciation.
