1. Infertility cases, due to very low sperm counts in the ejaculates, could be corrected by artificial insemination (AI) technique using a third person as the sperm donor.

2. Occurrence of more than one ovule in a embryo is referred to as polyembryony.

3. In a lactating mother, menstruation does not occur even if fertilisation happens.

4. Infertility cases due to inability of the male partner to inseminate the female could be corrected by artificial insemination (AI) technique.

5. The Indian population which was around 2000 million in 2011.

6. The presence of X or Y chromosome in the sperm determines the sex of the embryo.

7. The mammary tubules of each mammary lobe join to form a lactiferous duct.

8. The total number of conceived pregnancies in a year all over the world is 550 millions.

9. Ovules are present in the style.

10. The total number of conceived pregnancies in a year all over the world is 250 millions.

11. Pollen grains are well-preserved as fossils because of the presence of intine.

12. The generative cell has an abundant food reserve.

13. The Indian population which was around 2000 billion in 1900.

14. The mammoth glands are one of the male secondary sexual characteristics.

15. The ovaries produce the female gamete (ovum) and some steroid hormones (ovarian hormones). Ovarian follicles in different stages of development are embedded in the stroma.

16. Pollen-pistil interaction involves all events from the landing of pollen grains on the ovary until the pollen tube enters the seed coat (when the pollen is incompatible) or pollen inhibition (when the pollen is compatible).

17. If hybrids are made into apomicts, there is segregation of characters in the hybrid progeny.

18. If 2n=14 in a plant, the endosperm nucleus contains 7 chromosomes.

19. The mammary tubules of each mammary lobule join to form a mammary duct.

20. Pollen grains of many species cause severe allergies.

21. Over 60% of angiosperm when the pollen grain is mature it contains three cells, the vegetative cell and two generative cells.

22. The Indian population was close to 3000 trillion during our independence.

23. In a lactating mother, the luteal phase comes after the ovulatory phase.

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

25. The morula becomes embedded in the endometrium of the uterus, is called implantation, and it leads to cleavage.

26. Infections or diseases transmitted through sexual intercourse are known as sexually transmitted diseases (STIs). Complications from STIs include pelvic inflammatory disease (PID), stillbirth, and infertility. Early detection facilitates better treatment of these diseases.

27. Several mammary ducts join to form a wider mammary ampulla which is connected to mammary ampulla through which milk is sucked out.

28. The Indian population which was crossed 1200 billion by 2011.

29. Some angiosperms produce more than one embryo in their seed, which is called polyembryony.

30. The morula becomes embedded in the myometrium of the uterus, is called blastulation, and it leads to pregnancy.

31. The follicular phase lasts until the ovulatory phase, whether or not the ovum is fertilised.

32. The embryo becomes embedded in the endometrium of the uterus, is called blastulation, and it leads to cleavage.

33. Nearly 45 to 50 million MTPs are performed in a year all over the world, which accounts for 1/5th of the total number of conceived pregnancies in a year.

34. In menstrual cycle, if the released ovum is not fertilised, the follicular phase does not secret estrogen.

35. In a lactating mother, menstruation takes place when fertilisation does not occur.

36. During ovulation, only one elephant is released per menstrual cycle.

37. The zygote formed by in-vivo fertilisation just before five mitotic divisions could be transferred into the uterus to assist those females who cannot conceive.

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

39. At the centre is a large central cell with three polar nuclei.

40. The zygote formed by in-vivo fertilisation before four mitotic divisions could be transferred into the uterus to assist those females who cannot conceive.

41. The male external genitalia is called a nose.

42. One of the problems of hybrids is that hybrid seeds have to be produced every year.

43. Today, a variety of contraceptive options are available, including natural, traditional, barrier methods, IUDs, pills, injectables, implants, and surgical methods.

44. After nine months of pregnancy, the fully developed foetus is ready for delivery.

45. The alveoli open into lactiferous duct.

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

47. The oviducts, uterus and vagina are male accessory ducts.

48. Endosperm is completely consumed by the developing ground nut’s embryo.

49. Groundnut consumes its endosperm before seed maturation.

50. The zygote formed by IVF before five mitotic divisions could be transferred into the uterus.
