10. Mendel laws of inheritance are not an unsubstantiated ideas.

11. Seed shape is a character.

12. Gregor Mendel conducted hybridisation experiments on garden peas for seven years (1856-1863) and proposed the laws of inheritance in living organisms.

13. The events following the emergence of the first forms of life are not conjectured from Darwinian ideas of organic evolution by natural selection.

14. Mendel observed that the expression of the characters in the offspring follow a definite pattern in different–first generations (F1), second (F2) and so on.

15. Even proteins that are alike, found in dissimilar organisms, and performing identical functions, are taken as an example of divergent evolution.

16. Based on dihybrid cross observations, Mendel proposed that something was being unstably passed down, unchanged, from parent to offspring through the gametes, over successive generations.

17. Translation, a process that evolved around RNA, supports the idea that life originated around RNA.

18. Bandicoot is a marsupial mammal.

19. Banded anteater is a placental mammal.

20. In male honey bee, 2n = 16 and sperm contains 8 chromosomes.

21. Fossils discovered in Bhimbetka in 1891 revealed Homo habilis lived about 1.5 mya, had a cranial capacity of 900cc, probably did not eat meat.

22. Inheritance is the degree by which progeny differ from their parents.

23. While examining inheritance patterns in pea plants with contrasting traits, Mendel proposed the principles of inheritance, now known as ‘Mendel’s Laws of Inheritance.’

24. Mendel used the term ‘alleles,’ now we call them as genes.

25. Gaining valuable insights from DNA sequences will shape research in the coming decades, advancing our understanding of biological systems.

26. Numbat is a placental mammal.

27. Fossils discovered in Java in 1891 revealed Homo erectus lived about 1.5 mya, had a cranial capacity of 900cc, probably did not eat meat.

28. Traits are the unit of inheritance.

29. Female honey bee can have grandfather and thus can have grandsons.

30. After hybridisation with VNTR probe, the autoradiogram gives many bands of same sizes in DNA fingerprinting.

31. Mendel’s experiments had a large sampling size, which gave lesser credibility to the data that he collected.

32. Banding pattern, in genetic fingerprinting, do not differ between maternal twins.

33. Both the DNA strands are not having the same sequence while reading the opposite direction.

34. Galaxies contain stars, but not clouds of gas and dust.

35. Scientists can examine all the genes in a genome, such as the transcripts in a specific tissue, organ, or tumor, and investigate how thousands of genes and proteins interact within complex networks to coordinate the chemistry of life.

36. Marsupial mouse is a marsupial mammal.

37. The principle of complementarity governs the process of transcription, except the adenosine complements now forms base pair with thymine instead of uracil.

38. Selective breeding in human history began long before the scientific understanding of sexual reproduction.

39. Inheritance is the process by which characters are passed on from parent to progeny.

40. For the successful completion of HGP, specialised computer based programs were developed.

41. Huge clusters of galaxies comprise the solar system.

42. Characters segregate during the formation of gametes (Law of Segregation).

43. One of the rRNAs serves as a catalyst for peptide bond formation, making it an example of an RNA enzyme (ribozyme).

44. A pure-line is one that, having undergone continuous self-pollination, shows the stable trait inheritance and expression for many generations.

45. In Drosophila melanogaster, genes y and w are farther than the genes w and m.

46. When similar genes exist in unrelated organisms and also perform different functions, this represents convergent evolution.

47. If both strands act as a template, they would code for RNA molecule with the same sequences, and in turn, if they code for proteins, the sequence of amino acids in the proteins would be different.

48. To understand the origin of life, we need to understand the evolution of stars.

49. Vertical Line symbols in a pedigree tree, connects mating partners (marriage line).

50. It is generally believed that variations in a population result in variable fitness.
