What would happen if syngamy does not occur?

1: Introduction to syngamy
Syngamy (fertilisation) refers to the process of fusion of two gametes (male and female) during sexual reproduction leading to the formation of zygotes.

2: Absence of syngamy
Absence of syngamy will lead to absence of fertilisation. This will lead to non-formation of zygotes and subsequent offspring. Hence, for sexually reproducing organisms, this will be a hindrance to ensure the continuity of species.
