हिन्दीDuring double fertilisation in an angiosperm embryo sac, the events of syngamy and triple fusion involve the fusion of how many total nuclei, respectively?
Correct answer · Option 1
2 and 3
Explanation
Syngamy involves the fusion of 2 haploid nuclei (one male gamete + egg nucleus). Triple fusion involves the fusion of 3 haploid nuclei (one male gamete + two polar nuclei). Thus, 2 and 3 nuclei are involved.
