4. Father of Genetics is: Mendel or Hooke

5. Father of Genetics is: Mendel

6. What kind of organisms did Mendel work with? Fruit flies or Peas

7. What kind of organisms did Mendel work with? Peas

8. Parent generation F1 or P1

9. Parent generation P1 Stands for Parent

10. First and second generation of offspring F1 and F2 or G1 and G2

11. First and second generation of offspring F1 and F2F = “Filial” Latin for Offspring

12. An allele that hides the presence of another allele Recessive Dominant

13. An allele that hides the presence of another allele Dominant

14. An allele that is hidden by the presence of another allele Recessive Incomplete

15. An allele that is hidden by the presence of another allele Recessive

16. Why did recessive traits disappear in the F1 generation and return in the F2 generation? COMPLETE DOMINACE OR SEGREGATION

17. Why did recessive traits disappear in the F1 generation and return in the F2 generation? Complete DominaceAND Segregation

18. Complete Dominance – Parent generation were pure Domiant and Recessive for traits: TT x tt so F1 generation all were heterozygous: Tt and only showed the dominant trait so the recessive trait “disappeared” or was hidden. • Segregation – using a Punnett square we can see that when the F1 generation are crossed with each other: Tt x Tt, ¼ of the offspring will have the recessive trait “reappear” because during meiosis – alleles separate or segregate and offspring get only one allele from Mom and one allele from Dad Explanation

19. Punnett Squares

20. T Dominant or Recessive

21. T Dominant (capital letTer)

22. tt Homozygous or heterozygous

23. tt Homozygous (letters identical)

24. Ll Homozygous or Heterozygous

25. Ll Heterozygous (Different cases – one lower and one upper)

26. If Black is dominant what are 2 possible genotypes for black cats? BB bb or Bb BB

27. If Black is dominant what are 2 possible genotypes for black cats? BB or Bb both will look Black because both have at least one dominant allele

28. What is the phenotype for this plant: tt, Tall is dominant to short Short Medium

29. What is the phenotype for this plant: tt, Tall is dominant to short short

30. What are the genotypes of these parents: • Heterozygous for tall x Homozygous for short Tt x tt or TT x tt

31. What are the genotypes of these parents: • Heterozygous for tall x Homozygous for short Tt x tt

32. The appearance of an organism Genotype or Phenotype

33. The appearance of an organism Phenotype - Physical Appearance

34. What is the genotype of a plant that is white, when dominant trait is Green? ww or gg

35. What is the genotype of a plant that is white, when dominant trait is Green? gg The dominant trait determines the letter used, recessive traits are always shown in lower case of dominant letter

36. R r R r R = round, r = wrinkled Cc? What genotype goes here?

37. R r R r Cc? What genotype goes here? rr

38. R r R r Cc? What Phenotype goes here?

39. R r R r Cc? What Phenotype goes here? wrinkled

46. Complex inheritance

47. A trait with multiple alleles Blood type or skin color

48. A trait with multiple alleles Blood type - A, B, o (skin color has multiple genes and a whole range of in between phenotypes)

49. RR = red Rr= red rr=white What kind of dominance? Complete or incomplete

50. RR = red Rr= red rr=white What kind of dominance? Complete
