24. Endosperm is not completely consumed by the developing ground nut’s embryo.

25. Transferring apomictic genes into hybrid varieties is non-beneficial.

26. In coconut, the endosperm remains present even after seed maturation.

27. Nearly 45 to 50 million MTPs are performed in a year all over the world, which accounts for 2/5th of the total number of conceived pregnancies in a year.

28. The vegetative cell floats in the cytoplasm of the generative cell.

29. Transferring apomictic genes into hybrid varieties is beneficial.

30. MTPs are also essential in certain cases where continuation of the pregnancy could be harmful or even fatal to the mother.

31. In menstrual cycle, if the released ovum is not fertilised, during the luteal phase hCG is produced.
