Gregor Mendel

  • Discovered that certain traits occur in offspring without any blending

  • Example: pea plants were either purple or white

  • not blended

Alleles

Alleles are represented by letters (can be ANY letter!)

Slide image

19

Alleles

Capital letters = dominant alleles

lowercase letters =recessive alleles

Slide image

20

Slide image

21

Dominant

  • Dominant alleles are always seen (if present)

  • capital letters

Slide image

22

Recessive

  • Recessive alleles are hidden (unless there is no dominant present)

  • lowercase

  • green in this example-->
