Syngamy:- It is the fusion of two entire gametes ( one male and the other is female) to form a zygote. The fertilization includes all the associated events that ultimately leads to the syngamy.
Types of Syngamy:-a) Regards to the fusion of gametes:-
i) Endogamy:- It involves self- fertilization, i.e the fusion of two gametes of the same parent.So, it is , thus, uniparental. E.g tapeworm.
ii)Exogamy:- It involves crosss- fertilization, i.e the fusion of two gametes formed by different parents. So, it is, thus biparental.e.g frog, rabbit, human.
b) Regards to the structure of fusing gametes:-
i)Isogamy:- In this the fusing gametes are similar in structure but they have behavioural differences. In this , the gametes produced by one parentdonot fuse with each other.So the gametes similar morphologically are known as isogametes e.g as in protozoans .and the fusion is known as isogamy.
ii)Anisogamyor Heterogamy:- In this the fusing gametes are diffrent in form, size, structure, and behaviour . Sucha gametes rae known as anisogametes or heterogametes and their fusion is known as anisogamy or heterogamy . e.g as in frog, human.
