A unique feature of angiosperm fertilization is the formation of both a zygote and an endosperm nucleus. If a mutation occurred preventing the fusion of one of the male gametes with the polar nuclei, what would be the MOST likely direct consequence?
Endosperm would not develop, impacting seed viability.
The zygote would fail to form, preventing embryo development.
A triploid zygote would form instead of a diploid zygote.
The ovule would develop into a seedless fruit.
Researchers are studying a mutant plant where the pollen tube fails to deliver the male gametes to the embryo sac. Which structure(s) would be ABSENT in the ovule of this mutant plant following pollination?

Both zygote and endosperm
Neither zygote nor endosperm
