Question

In the case of adventive polyembryony, if an embryo develops from the synergid and another from the nucellus, then synergid embryo will be ___________ and the nucellar embryo will be __________ .

• A. haploid, haploid
• B. diploid, diploid
• C. haploid, diploid
• D. diploid, haploid

Answer 1

The correct option is C haploid, diploid

The phenomenon where two or more embryos develop from a single fertilized egg is polyembryony. In adventive embryony, an embryo develops directly from diploid (2n) cell other than egg, like that of the nucellus and integuments which eventually give rise to multiple embryos of diploid nature
If the synergids are taking part in polyembryony then the embryo would be haploid as the synergid is haploid genetically.
