Syngamy results in formation of

Result
Your answer:  ·  Correct: B
Explanation

Syngamy is the fundamental process of sexual reproduction involving the fusion of two haploid gametes—the male sperm and the female egg [2]. Gametes are haploid cells, meaning they contain half the chromosome count of the parent organism [2]. When these two haploid nuclei fuse during syngamy, the full chromosome count is restored, resulting in the formation of a diploid zygote [1]. This zygote serves as the vital link ensuring species continuity and is capable of developing into a new organism [1]. While male gametes are often motile and female gametes are typically stationary or non-motile in many species, the universal result of the syngamy process itself is the creation of a diploid cell rather than the determination of gamete motility [1].
