1. Lemur is a placental mammal.

2. Flower position is a character.

3. Understanding mutations has aided in the study of genetic disorders.

4. Banded anteater is a marsupial mammal.

5. Mendel selected 14 true-breeding pea plant varieties, as pairs which were similar except for six character with contrasting traits.

6. Variation is the process by which characters are passed on from parent to progeny; it is the basis of heredity.

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

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

9. The operator region is not adjacent to the promoter elements in all operons.

10. Mendel conducted cross pollination experiments using several true-breeding pea lines.

11. Huge clusters of galaxies comprise the earth.

12. Alignment of the DNA fragments’ sequences based on overlapping was humanly possible.

13. Not all characters show true dominance recessive relationship.

14. In HGP, 46 human chromosomes were sequenced.

15. Chromosomal aberrations are easily studied through karyotype analysis.

16. Some traits are dominant over others, meaning dominant traits are expressed when the factors are in a heterozygous condition (Law of Dominance).

17. In bacteria, each operon has its specific operator and specific repressor.

18. Biochemical dissimilarities are pointing to the same shared ancestry as structural similarities among similar organisms.

19. Shaded Circle/Square symbol in a pedigree tree, represents an individual who does not express the trait or disorder.

20. DNA from a single cell is enough to perform DNA fingerprinting analysis.

21. Mouse is a marsupial mammal.

22. Similar proteins in similar organisms performing dissimilar functions is an example of convergent evolution.

23. Humans knew from as early as 8000-1000 B.C. that one of the causes of variation was hidden in asexual reproduction.

24. DNA fingerprinting, a technique that detects individual variations within a population’s DNA, operates on the principle of polymorphisms in DNA sequences.

25. In eukaryotes, each operon has its specific operator and specific repressor.

26. Flippers of Penguins and Dolphins are anatomically similar structures, though they perform similar functions.

27. Siblings sometimes look so similar to each other or sometimes even so different. 

28. Wolf is a placental mammal.

29. Flying squirrel is a placental mammal.

30. Biochemical similarities are pointing to the different shared ancestry as structural similarities among diverse organisms.

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

32. Linkage maps corresponded to arrangement of genes on a chromosome.

33. Male honey bee do not have father and thus cannot have sons.

34. Bobcat is dissimilar to Tasmanian tiger cat.

35. Mouse is similar to Marsupial mouse.

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

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

38. Mendel suggested that the ‘factors’ (later termed genes) controlling traits are found in pairs, called alleles.

39. Huge clusters of galaxies comprise the universe.

40. Similarities in proteins performing a given function among diverse organisms give clues to common ancestry.

41. Autoradiogram bands in a nylon membrane give a characteristic pattern for an individual DNA.

42. During HGP, the fragment sequences were subsequently annotated and were assigned to each chromosome.

43. Tubers of potato and sweet potato are anatomically similar structures, though they perform dissimilar functions.

44. The geological history of earth closely correlates with the biological history of a species.

45. The star we see today is an object whose emitted light started its journey millions of years back.

46. Mouse is a placental mammal.

47. Similar proteins in dissimilar organisms performing dissimilar functions is an example of convergent evolution.

48. Seed colour is a character.

49. Early human (8000 – 1000 B.C.) do not know about inheritance.

50. Mapping of human genome was generated using information on polymorphism of restriction endonuclease recognition sites, and some repetitive DNA sequences known as microsatellites.
