Question

Process of fusion between male gamete and egg nuclei is

• A. Syngamy
• B. Double fertilization
• C. Conjugation
• D. Triple fusion

Answer 1

The correct option is A Syngamy

• Syngamy is the fusion of male gamete with the egg cell and results in the formation of a diploid zygote.
  
• Double fertilization is a unique phenomenon in angiosperms in which one male gamete fuses with the egg cell and other male gamete fuses with the secondary nucleus i.e. syngamy and triple fusion occur simultaneously.
  
• Conjugation is the transfer of genetic material between two bacteria by means of conjugation tube.
  
• Triple fusion is the fusion of male gamete with the secondary nucleus (formed from fusion of two polar nuclei) resulting in the formation of triploid primary endosperm mother cell.
  

So, the correct answer is A.
