    Heredity
  22. Father of genetics 
    Gregor Mendel
  23. 1st to Describe how genes can be passed to offspring, using alleles
    Mendel
  24. Used careful studies of pea plants to demonstarte heredity
    Mendel
  25. What is yellow in a pea plant?
    The dominant color
  26. What is Green in the Pea Plant?
    The recessive color
  27. What controls an organism's form and function?
    Genes on a chromosome
  28. Different forms a gene has for a trait
    Alleles
  29. Give 2 examples of an Allele for:
    Tall Pea Plant
    TT or Tt
  30. Give an example of an Allele for:
    Short Pea Plant
    tt
  31. Pollen from the stamen is transferred to the pistil of the same plant. 
    1 parent involved.
    Self-Pollination
  32. Pollen from one pea plant is transferred to the pistil of another pea plant.
    2 Parents Involved.
    Crosspollination
  33. Plants that are pure for a trait always produce what?
    Offspring with that trait when they are self pollinated
  34. How many parents are involved in Self-pollination?
    1
  35. How many parents are involved in Crosspollination?
    2
  36. Alleles that are identical
    Pure
  37. Another word for Homozygous?
    Pure
  38. Another word for Heterozygous
    Hybrid
  39. How many total pure breeding strains did Mendel obtain?
    14
  40. What kind of offspring does Cross Pollination make?
    Hybrids
  41. What is the parent generation called?
    P1
  42. What is the offspring generation called?
    F1
  43. 2 Different parents with different traits
    Hybrid
  44. What were Mendels results?
    Genes controlling heredity occur in pairs
  45. The factor that masks the other, preventing it from showing its affect?
    Dominant
  46. When a dominant allele overshadows a recessive allele
    Principle of Dominance and Recessiveness
  47. Explain the Law of Segregation
    There are 2 copies of a gene for each trait. These copies separate during the formation of sex cells in meiosis I and recombine during fertilization.
  48. Genes for a different trait are inherited independently of one another
    Law of Independent Assortment
