1. Based on monohybrid cross observations, Mendel proposed that ‘factors’ were being stably passed down, unchanged, from parent to offspring through the gametes, over successive generations.

2. Replication is a systemic process, whereas the transcription is a localised process.

3. Evidence shows Australopithecines lived 2 mya, in Australian grasslands, hunted with stone weapons but essentially ate meat.

4. In male honey bee, n = 16 and sperms are produced by mitosis.

5. When Mendel studied the inheritance of two traits simultaneously, he found that the factors assort independently and combine in various permutations and combinations, known as the Law of Independent Assortment.

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

7. A true-breeding line is one that, having undergone continuous self-pollination, shows the stable trait inheritance and expression for several generations.

8. The resemblance of progeny to their parents in terms of morphological and physiological traits has long intrigued biologists.

9. In male honey bee, n = 16 and sperms are produced by meiosis.

10. The offsprings are identical to their parents.

11. Failing to derive meaningful knowledge from DNA sequences will not shape research in the coming decades, leaving our understanding of biological systems stagnant.

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

13. The process of copying genetic information from one strand of the DNA into other strand of DNA is termed as transcription.

14. Banding pattern, in genetic fingerprinting, differs from individual to individual in a population.

15. Tasmanian tiger cat is a marsupial mammal.

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

17. 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.

18. The brain capacities of the hominids were between 450-600cc.

19. The accessibility of promoter regions of prokaryotic DNA is in all cases regulated by the interaction of proteins with sequences termed operators.

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

21. Both DNA and RNA cannot function as genetic material, and DNA is not structurally and chemically more stable, making it a worse genetic material.

22. Mendel was the first to study the genetics phenomenon systematically.

23. In bacteria, each operon has its non-specific operator and specific repressor.

24. Some mutations involve changes in the entire set of chromosomes (polyploidy) or a subset of chromosomes (aneuploidy).

25. Both the DNA strands are copied during transcription.

26. The origin of life is not considered as a normal event in the history of universe.

27. Evidence shows Australopithecines lived 3 mya, in East African grasslands, hunted with stone weapons but essentially ate meat.

28. Among the stories of evolution of individual species, the story of evolution of modern man is most interesting and appears to parallel evolution of human brain and language.

29. The accessibility of promoter regions of prokaryotic DNA is in numerous instances not regulated by the interaction of proteins with sequences termed operators.

30. The case where similar genes appear in dissimilar organisms and carry out similar functions is likewise considered convergent evolution.

31. In Drosophila melanogaster, crossing between gene w and m does not produce Mendelian ratio.

32. Fossils discovered in Bhimbetka in 1891 revealed Homo erectus lived about 15 mya, had a cranial capacity of 650cc, probably ate meat.

33. Seed shape is a character.

34. The subsequent events as to what happened to the first form of life is a conjectured story based on Darwinian ideas of organic evolution by natural selection.

35. The brain capacities of the hominids were between 1650-1800cc.

36. Numerous new areas of research and opportunity have not emerged due to the human genome project.

37. Numbat is a placental mammal.

38. Traits are the unit of inheritance.

39. The offsprings are genetically identical to their parents.

40. Gaining valuable insights from DNA sequences will not require the expertise and creativity of scientists from varied disciplines, and collaboration across sectors may not be essential.

41. Nucleic acids, which are long polymers of nucleotides, serve essential functions in storing and transferring genetic information.

42. Arabic Numerals in a pedigree tree indicate generations (I, II, III, etc.).

43. Alfred Miller, a naturalist who worked in the Archipelago, had also come to conclusions similar to Darwin around the same time.

44. 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.

45. Linkage maps correspond to the arrangement of genes on a chromosome.

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

47. Similar genes in similar organisms performing similar functions is an example of divergent evolution.

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

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

50. Half-Shaded Circle/Square symbol in a pedigree tree, indicates a carrier of a dominant trait (heterozygous).
