  1. Wrinkled and round garden peas, the phenotypic traits in one of Mendel’s monohybrid crosses.

  2. Da Vinci Code Offends Albino CommunitybySandra Lim May 22nd 2006 Will it never end? It seems that The Da Vinci Code cannot not offend everyone on the planet; this time, it's the albino community that is angry with the movie for depicting albinos as evil villians. Michael McGowan, the head of the National Organization for Albinism and Hypopigmentation, had asked the movie's production people not to bleach Silas the albino monk's hair or make his eyes red, but to no avail. Again, I'm no fan of the book and found the albino-monk-assassin scenes most laughable and fairly annoying. More amusing to me is this profile of Victor Varnado, an actor-comedian who actually auditioned for the part of Silas, but lost out to Paul Bettany. According to Varnado, "I think that albinos should have all [albino] roles . . . Painting a guy to look like an albino is like the blackface of albinism!" Hmm, the blackface of albinism. I'm still thinking about that one. Apparently Varnado just wasn't physically intimidating enough to play Silas.

  12. The monohybrid cross between tall (D) and dwarf (d) pea plants. Individuals are shown in rectangles, and gametes in circles.

  13. Test cross of a single character. In (a), the tall parent is homozygous, but in (b), the tall parent is heterozygous. The genotype of each tall P1 plant can be determined by examining the offspring when each is crossed to a homozygous recessive dwarf plant.

  14. Dihybrid Cross

  15. The F1 heterozygous plants are self-fertilized to produce an F2 generation, which is computed using a Punnett square. Both the phenotypic and genotypic F2 ratios are shown.

  16. F1 and F2 results of Mendel’s dihybrid crosses, where the plants on the top left with yellow, round seeds are crossed with plants having green, wrinkled seeds, and the plants on the top right with yellow, wrinkled seeds are crossed with plants having green, round seeds.
