The common grackle is a species of robin-sized blackbirds that are fairly common (hence the name) over most of the United States. Suppose that long tails (L) were dominant to short tails (l) in these birds. A female short-tailed grackle mates with a male long-tailed grackle whose mother was short tailed and father had a long tail. What is the probability of a short-tailed offspring?
