11. In Drosophila melanogaster crossing between gene w and m produces Mendelian ratio.

12. Bobcat is a placental mammal.

13. Male honey bee do not have grandfather and thus cannot have grandsons.

14. If we use alphabetical symbols for each gene, then the capital letter is used for the trait expressed at the F1 stage and the small alphabet for the other trait.

15. Those organisms are not fit in an environment, therefore, will survive more and hence are rejected by nature.

16. Mendel conducted artificial pollination experiments using many true-breeding pea lines.

17. The principle of complementarity governs the process of transcription without any exception.

18. The common ancestors may present at different periods in the history of earth.

19. Alignment of the DNA fragments’ sequences based on overlapping was computationally not possible.

21. Flying squirrel is a placental mammal.

22. Early human (8000 – 1000 B.C.) know about variation.

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

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

25. Despite the availability of whole-genome sequences and advanced high-throughput technologies, researchers are unable to address questions in a more systematic or broader manner.

26. In a pedigree tree, Roman Numerals: Indicate generations (I, II, III, etc.).

27. Traits contain the information that is required to express a particular trait in an organism.

28. Banding pattern, in genetic fingerprinting, do not differ between homozygotic twins.

29. Huge clusters of galaxies comprise the earth.

30. Different combinations of gametes are theoretically represented in a square tabular form known as ‘Punnett Square.’

31. Biochemical similarities are pointing to the different shared ancestry as structural similarities among similar organisms.

32. Fossils discovered in Java in 1891 revealed Homo habilis lived about 1.5 mya, had a cranial capacity of 900cc, probably ate meat.

33. The Big Bang Theory talks of a singular huge explosion imaginable in physical terms.

34. The strength of linkage between y and w is lower than w and m.

35. Considering the size of the sun, the universe is indeed a speck.

36. Fossils discovered in Java in 1891 revealed Homo erectus lived about 1.5 mya, had a cranial capacity of 900cc, probably ate meat.

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

38. Today genetic maps are extensively used as a starting point in the sequencing of whole genomes as was done in the case of the Human Genome Project

39. Formation of double stranded RNA would prevent RNA from being translated into protein, and the exercise of transcription would become a futile one.

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

41. In all cases, the sequences of the operator bind a repressor protein.

42. Klinefelter’s syndrome – Big and wrinkled tongue.

43. Flippers of Penguins and Dolphins are an example of analogous structures and for convergent evolution.

44. 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.

45. The genetic code is not read by tRNA, which does not act as an adapter molecule.

46. Early human (8000 – 1000 B.C.) know about scientific basis of inheritance.

47. Fossils discovered in Java in 1891 revealed Homo habilis lived about 15 mya, had a cranial capacity of 900cc, probably ate meat.

48. Variation is the process by which characters are passed on from progeny to parent.

49. A point mutation is a change of a single base pair in DNA.

50. Mendel’s laws were later extended into the ‘Chromosomal Theory of Inheritance.’ However, it was discovered that Mendel’s Law of Independent Assortment does not apply to genes located on the same chromosome.
