Question

In double fertilisation

• A. One male gamete fuses with the antipodal, while the other fuses with the diploid nucleus
• B. One male gamete fuses with the egg and the other fuses with the secondary nucleus
• C. One male gamete fuses with the egg, while the other fuses with the antipodal
• D. Two male gametes fuse with two eggs

Answer 1

The correct option is A

One male gamete fuses with the antipodal, while the other fuses with the diploid nucleus

One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing syngamy. This results in the formation of a diploid cell, which is the zygote. The other male gamete moves towards the two polar nuclei located in the central cell and fuses with them to produce a triploid primary endosperm nucleus. This completes the process of double fertilisation.
