CSET Genetics And Evolution

Subjects : cset, science, genetics
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Features of different species tat are similar in function but not necessarily in structure and in which the similarity is not the result of common ancestry






2. A process that results in an allele having a different probability of remaining in the gene pool compared with that of another allele






3. When F1 is fully fertile but F2 has low fertility (rice - cotton)






4. The specific location of a gene on a chromosome






5. DNA that is coiled around proteins






6. A limb with five digits (fingers)






7. The type of environment in which an organism or group normally lives or occurs






8. Predicts the possible outcome of a genetic cross.






9. Form of reproductive isolation in which tere are differences in species courtship behavior






10. Independent segregation of genes during the formation of gametes






11. Uses metamorphic or igneous rock - calculates the age of an object by assessing the amount of radioactive element still present in the organism. Radioactive elements are slowly lost over time because of decay.






12. A copy of a gene is made during a process called this






13. All the factors in an organism's surroundings that can potentially affect it






14. Structure present in an organism however does NOT have a known function. May link organisms with similar vestigial structures. Example: appendix - coccyx bone - whale leg bones.






15. The movement of individuals into an area






16. Two alternative forms of a gene e.g Tall vs Short






17. What is one benefit for having two strands of DNA?






18. Because of base pairing in DNA the amount of






19. It means chromosomes are paired. One of each chromosome in a pair originates from the father and one from the mother. They affect the same trait - but don't necessarily cause the same expression of the trait.






20. A process where the organisms that have traits that aid in its survival (adaptive traits) will reproduce to pass that trait to futher generations thus increasing the frequency of that trait in the population. Vice versa traits that reduce the chance






21. Another term for pure breeding






22. Layers of compressed sedimentary rock demonstrate the order or sequence at which events occurred. Cannot delineate the exact point of time - but is able to distinguish the order of events.






23. During transcription an RNA molecule is formed






24. A type of natural selection in which genetic diversity decreases as the population stabilises on a particular trait value






25. Selection against one end of a range of variation - resulting in a progressive change in allele frequency






26. Impression made from a organism in soft material such as sand or mud.






27. An ancestor that two or more descendants have in common






28. Similar DNA sequences or protein structures (such as hemoglobin) may link different species to a similar ancestor.






29. Found only in that country






30. Organisms with similar functions - but different underlying structure. Example: bird and insect wing. These structures do NOT show a common ancestral link.






31. A point of overlap of paired chromatids at which fusion and exchange of genetic material (crossing over) occurs during prophase I of meiosis.






32. Is any chromosome that is not a sex chromosome.






33. Building block of a nucleic acid (DNA and RNA)






34. A body cell






35. The complete genetic material contained in an individual






36. Evolution of the earth - which is hypothesized to have been formed over 4.6 billion years ago.






37. Movement of alleles into or out of a population due to the migration of individuals to or from the population






38. A trait that masks the expression of another trait






39. Process by which an organism is slowly turned to stone as the body is replaced by minerals.






40. Change to a chromosome in which a fragment of the chromosome is removed






41. Change to a chromosome in which a fragment of one chromosome attaches to a nonhomologous chromosome






42. Shows how the embryos of different groups resemble each other at particular stages. Similarities indicate groups may share a common ancestor






43. Genes contain instructions for assembling






44. Used radioactive sulfur and radioactive phosphorus to determine that DNA is the genetic material - by demonstrating that it is DNA that is injected by bacteriophages into bacterial cells during infection






45. Selection acting against the middle of a range of variation






46. The gradual changes in gene frequencies in a population due to random events






47. Chromosomes that determine the sex of an individual. These are X for female and Y for male. The female egg is an X while the male sperm can be X or Y






48. One of the identical rods of a chromosome.






49. Innate trait; shared ancestry






50. Organisms with a similar underlying structure - but different function. Example: bird - bat and dolphin 'arm'. Shows a common ancestral link.
