Question

when two light yellow flowers (yw) are crossed, there are four equally likely possible outcomes for the genetic makeup of the offspring: yellow (yy), light yellow(yw), light yellow(wy), and white (ww). if two light yellow snapdragons are crossed, what is the probability that the offspring will be (a) light yellow, (b) yellow, and (c) white?
(a) if two light yellow snapdragons are crossed, the probability that the offspring will be light yellow is \\( \frac { 1 } { 2 } \\).
(do not round.)
(b) if two light yellow snapdragons are crossed, the probability that the offspring will be yellow is \\( \square \\).
(do not round.)

Explanation:

Step1: Recall the probability formula

The probability of an event \(E\) is given by \(P(E)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the total number of outcomes \(n = 4\) (YY, YW, WY, WW).

Step2: Find the probability for yellow

For the event of the offspring being yellow (YY), the number of favorable outcomes \(m = 1\). Using the formula \(P=\frac{m}{n}\), we substitute \(m = 1\) and \(n=4\).

Answer:

\(\frac{1}{4}\)
