Question
A pink-flowering plant is of genotype RW. If two such plants are crossed, we obtain a red plant (RR)
with probability 0.24, a pink plant (RW or WR) with probability 0.58, and a white plant (WW) with
probability 0.18, as shown in the table. What is the expected number of W genes present in a crossing
of this type?
The expected number of white genes (W) is.
