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