Vocab Vocab Overview Genetics

  1. 1. Allele allele allele
  2. 2. Allele allele allele one form of a gene
  3. 3. Chromosome
  4. 4. Chromosome A bundle of dna that has many different genes
  5. 5. Codominance
  6. 6. Codominance When both alleles of a gene show up as a trait
  7. 7. Dominant Allele B, W, F, T, A The trait or allele that always shows up over a recessive allele.
  8. 8. Dominant Allele B, W, F, T, A
  9. 9. Recessive Allele d, b, t, w, a
  10. 10. Recessive Allele d, b, t, w, a The trait or allele that will not show up in the presence of a dominant allele.
  11. 11. Gene Gene
  12. 12. Gene Gene A segment of a chromosome that codes for one specific trait. Usually made of two alleles.
  13. 13. Genetics
  14. 14. Genetics The study of heredity or how traits are passed from parents to offspring
  15. 15. Genotype Bb, WW, cc,
  16. 16. Genotype Bb, WW, cc, The genetic makeup of an organism.
  17. 17. Phenotype Example. Orange head, white body, long fins, fat belly.
  18. 18. Phenotype Example. Orange head, white body, long fins, fat belly. An organisms set of traits.
  19. 19. Heredity
  20. 20. Heredity The process of traits being passed from parents to offspring.
  21. 21. Heterozygous Bb
  22. 22. Heterozygous Bb When two alleles for a gene are different.
  23. 23. Homozygous BB
  24. 24. Homozygous BB When two alleles for a gene are identical.
  25. 25. Hybrid
  26. 26. Hybrid An organism that has a mixture of traits.
  27. 27. Incomplete Dominance
  28. 28. Incomplete Dominance When a trait for a dominant allele blends with the traits for a recessive allele.
  29. 29. Meiosis
  30. 30. Meiosis The process of creating four sex cells with half the number of chromosomes as the original.
  31. 31. Mitosis
  32. 32. Mitosis The process of making an exact copy of a cell.
  33. 33. Mutations
  34. 34. Mutations When a gene or DNA becomes changed.
  35. 35. Probability
  36. 36. Probability The likeliness of something happening.
  37. 37. Punnett Square
  38. 38. Punnett Square A chart used to calculate the probability of offspring getting certain traits.
  39. 39. Purebred
  40. 40. Purebred When an organism has genes with all of the same alleles. All genes are homozygous.
  41. 41. Selective Breeding
  42. 42. Selective Breeding When you control what traits an organism has by selecting to breed parents with desired traits.
  43. 43. Trait
  44. 44. Trait A physical feature of an organism such as hair color.
  45. 45. Asexual Reproduction
  46. 46. Asexual Reproduction Reproduction involving only one parent
  47. 47. Sexual Reproduction
  48. 48. Sexual Reproduction Reproduction involving more than one parent
  49. 49. Genetic Engineering
  50. 50. Genetic Engineering Changing an organisms genes in order to control it's traits
  51. 51. Offspring
  52. 52. Offspring new organisms produced by a living thing
