When two purple flowers (RB) are crossed, there are four equally likely possible outcomes for the genetic makeup of the offspring: red (RR), purple(RB), purple(BR and blue (BB). If two purple snapdragons are crossed, what is the probability that the offspring will be (a) purple, (b) red, and (c) blue? . . . (a) If two purple snapdragons are crossed, the probability that the offspring will be purple is (Do not round.)
