Simple Dominance. Monohybrid Cross T = tall and f = dwarf; tall Is dominant. Cross a tall pea plant with a heterozygotic plant. What percentage of the offspring will be tall? Simple dominance, monohybrid cross. B = brown fur color in rabbits, b = white fur color; brown is dominant. Predict the outcome from a cross between a brown rabbit and a white rabbit if you know that the brown rabbit’s mother had white fur. Incomplete dominance, monohybrid cross. C^RC^R = red, C^RC^W= pink, C^WC^W = white. I have several pink flowered snapdragons, all of which came from a white flowered plant. What is the color of the other parental plant? I crossed a red flowered snapdragon with a white flowered snapdragon. What will be the phenotypic ratios from this pairing? Simple dominance, dihybrid cross. Y = yellow, y = green; R = round, r = wrinkled. Yellow is dominant to green and round is dominant to wrinkled. Cross the following: yyRR with YYrr. A. How many different phenotypes will you observe in the Fi generation and what are they? B. If a plant from the F_1 generation self-fertilizes and produces 1,000 offspring, how many of those offspring do you expect to have green, wrinkled seeds?
