Syngamy

Definition

Syngamy is the process of fusion between two gametes to form a zygote. It is a critical step in sexual reproduction among unicellular eukaryotic parasites.

5 Must Know Facts For Your Next Test

1. Syngamy ensures genetic diversity through the combination of genetic material from two different gametes.
2. It involves the fusion of haploid cells (gametes) to create a diploid cell (zygote).
3. In many unicellular eukaryotes, syngamy can occur immediately after meiosis.
4. The resulting zygote can undergo mitosis to develop into a mature organism.
5. Syngamy is distinct from other forms of genetic recombination like conjugation and transformation.
