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. Trait where heterozygous is a blending of two alleles






2. Individual that is heterozygous for two traits; shows the phenotype governed by the dominant alleles but carries the recessive alleles






3. A small simple structure (as a fertilized egg) from which new tissue can develop into a complete organism. It is also a cell






4. Is found in DNA






5. Type of rock made from small pieces of other rocks and organisms pressed together. Source of fossil preservation. Limited radioactive or absolute dating potential.






6. Evolutionary process in which a species or related species folllow different evolutionary paths to eventually become less related






7. Building block of a protein






8. Evolution of superficial phenotypic similarity of form as a result of similar selection pressures






9. A group of organisms whose members are sufficiently alike to be able to reproduce and produce fertile offspring and who are unable to reproduce with other such groups






10. A codon is made of...






11. The capacity of an individual of certain genotype to reproduce. It is usually equal to the proportion of the individual's genes in all the genes of the next generation






12. A fossil known to have lived in a particular geologic age that can be used to date the rock layer in which it is found






13. Change in a DNA sequence that affects genetic information






14. The inherited characteristic often masked by the dominant characteristic and not seen in an organism. e.g. Tt plant will still be tall. Where T is the dominant trait for tall and t is the recessive trait for small.






15. Change in allele frequencies as a result of the migration of a small subgroup of a population






16. Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest






17. Era of recent life that began about 66 million years ago and continues today; includes the first appearance Hominids






18. T or F A cloned organism has the same proteins as another organism






19. The study relating the evolution of new charateristics to changes in the genes controlling development






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






21. Independent segregation of genes during the formation of gametes






22. Natural selection that causes the frequency of a particular allele to move in one direction






23. Any preserved remains of an organism from the past. Usually found in sedimentary rock.






24. The sum total of an organism's requirements; its way of life






25. Features that are superficially similar but have different modes of development






26. Organ that serves no useful function in an organism






27. Nucleotides that control which amino acids are added during protein synthesis






28. Any agent that can cause a change in DNA






29. Natural disaster eliminates most of the population - members left contribute the alleles for the new population.






30. Types of rocks formed after exposure to very high heat. Because of the high temperatures - fossils are not able to be recovered from these types of rocks. Absolute or radioactive dating is possible - however.






31. One of the identical rods of a chromosome.






32. Consists of all genes - including all the different alleles - that are present in a population






33. Is active during transcription






34. Molecules that join together to form DNA and RNA. Monomers that make up a nucleic acid






35. Threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next






36. Actual remains of an organism such as bones - teeth - shells - etc.






37. Chromosomes are collections of many






38. A group of organisms of the same species occupying a given area.






39. A unique combination of traits that are passed down from one generation to another.






40. Situation in which allele frequencies remain constant






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






42. Populations that can interbreed with neighboring populations but not with populations separated by larger geographical distances






43. Gene

44. Breeding organisms with specific traits in order to produce offspring with identical traits






45. The evolutionary history/geneology of a group of organisms (a tree thingy)






46. Trait evolves overtime; NO common ancestry






47. Deoxyribonucleic acid carries the genetic code for the proper functioning of an organism. It is composed of 5 carbon sugar (deoxyribose) four bases Adenine - Thymine - Cytosine and Guanine. the sugar is bonded to a phosphate group. This forms a long






48. All the genes in a population. genes are added by reproduction and immigration and lost by death and emigration






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






50. The final product of transcription is...
