Across
  1. 2. By working with 2 traits at the same time, Mendel determined the law of independent assortment.
  2. 3. is when an allele affects over or more than one trait.
  3. 6. individuals that have only one member of the chromosome pair.
  4. 8. coming off to one character at a time. Also, Mendel first do this in his observation.
  5. 9. allele that is dominant in “autosomal dominant disorder”.
  6. 12. refers to the noticeable expression of the genes.
  7. 14. Explicit and appears more frequently resulting from interactions between gene alleles.
  8. 15. the phenotype was being affected by 2 alleles coming from each parent.
  9. 18. 1 in 25 is carrier, 1 in 2500 is affected.
  10. 19. produces spores not gametes.
  11. 22. a diploid organism’s both alleles are the same.
  12. 23. these are made of DNA.
  13. 29. heredity pattern that show one genetic factor involved.
  14. 30. inheritance by transmission from parents to offspring.
  15. 32. refers to organism that both alleles are missing for the same gene.
  16. 33. it is incurable hereditary disorder that progressively destroy the brain of those affected.
  17. 35. is a characteristic controlled by multiple genes.
  18. 36. a combination of parent’s phenotype.
  19. 39. (a disease) it is a dominant lethal condition that affects the brain.
  20. 40. hypothesis; possible explanation for hereditary.
  21. 41. Mendel is actually first to count this in crosses to a particular plant.
  22. 43. parent’s genes can be sorted and passed on. In here traits are separable.
  23. 45. Distinguishing quality; a sundry for the character.
  24. 46. red blood cells become distorted into____________. “Sickle-cell anemia” is a disorder that causes oxygen to be low which is not enough throughout the affected body.
  25. 48. the actual genetic makeup of an individual.
  26. 50. This part was shrug off for allogamy.
Down
  1. 1. a condition in which a person is born is born with additional toes or finger.
  2. 4. Mendel did this because he did not know the genotype of an individual expressing a dominant trait.
  3. 5. an interplay between the products of two genes in which the effect of one such gene by another is dependent in the mutation of one or more other genes.
  4. 6. have different alleles in an organism.
  5. 7. squares, used for an easy expression of the genotype probabilities.
  6. 10. mating and crossing in genetics.
  7. 11. probability that an event will happen in two or more different ways.
  8. 13. alleles shows incomplete dominance in this level.
  9. 16. reports the similarity and difference of the DNA sequence in the homologous alleles.
  10. 17. “Numerous gene inheritance” that is a member of any group of non-allelic genes.
  11. 20. this level has healthy and normal functional enzyme making if dominant to Tay-Sachs allele.
  12. 21. Mendel’s law that states a random gene copy are passed to each gamete.
  13. 24. the relative like hood of an event happening.
  14. 25. is when intermediate phenotype is present on the offspring.
  15. 26. breeding, referring to organisms that passes down same variety of phenotypic trait to their offspring over generations.

  23. 44. The DNA sequence of a gene often varies from one individual to another. ______ is alternate type of genes for each trait.
  24. 47. outlines biological relation of an organism and its ancestors.
  25. 49. Gregor Mendel, the father of genetics started breeding this in 1857.
